1 Introduction
Squeezing flow between parallel walls occurs in many indus-trial and biological systems The unsteady squeezing flowof a viscous fluid between parallel plates in motion normalto their own surfaces is a great interest in hydrodynamicalmachines The pioneer work and the basic formulation ofsqueezing flows under lubricationwere assumed by Stefan [1]In past researches over few decades Reynolds [2] analyzedthe squeezing flow between elliptic plates while Archibald[3] suggested the same problem for rectangular plates TheReynolds equation was studied for squeezing flows whichwere not sufficient for some cases as was demonstrated byJackson [4] and Usha and Sridharan [5] The study on themotion of electrically conducting fluid in the presence ofa magnetic field is called magneto hydrodynamics (MHD)In engineering the application of MHD can be seen inthe electromagnetic pump The pumping motion of thisdevice is caused by the Lorentz force This force is producedwhen mutually perpendicular magnetic fields and electriccurrents are applied in the direction perpendicular to theaxis of a pipe containing conducting fluid [6] The laws of

3 The Basic Steps of the Novel Algorithm
This section describes how to obtain a novel algorithm tocalculate the coefficients of the power series solution result-ing from solving nonlinear ordinary differential equations
resulting from using transforms ((8)-(10)) to find analytical-approximate solution These coefficients are important basesto construct the solution formula therefore they can becomputed recursively by differentiationways To illustrate thecomputation of these coefficients and derivation of the novelalgorithm we summarized the detailed new outlook in thefollowing steps
Step 1 Consider the nonlinear differential equation as fol-lows
119867(119891 (120578) 1198911015840 (120578) 11989110158401015840 (120578) 119891101584010158401015840 (120578) 119891(119899minus1) (120578) 119891(119899) (120578))= 0 (16)
and integrating (16) with respect to 120578 on [0 120578] yields119891 (120578) = 119891 (0) + 1198911015840 (0) 120578 + 11989110158401015840 (0) 12057822

(17)
where
119866 [119891 (120578)]= 119867(119891 (120578) 1198911015840 (120578) 11989110158401015840 (120578) 119891(119899minus1) (120578))

Step 2 Assume that
119866 [119891 (120578)] = infinsum119899=1
119889119899minus1119866 (1198910 (120578))119889120578119899minus1 (19)
rewriting (19)
119866 [119891 (120578)] = 119866 [1198910 (120578)] + 1198661015840 [1198910 (120578)] + 11986610158401015840 [1198910 (120578)]+ 119866101584010158401015840 [1198910 (120578)] + 1198661015840101584010158401015840 [1198910 (120578)] + sdot sdot sdot (20)
and substituting (20) in (17) we obtain
119891 (120578) = 1198910 + 1198911 + 1198912 + 1198913 + 1198914 + sdot sdot sdot (21)

We see that the calculations become more complicated in thesecond and third derivatives because of the numerous calcu-lations Consequently the systematic structure on calculationis extremely important Fortunately due to the assumptionthat the operator 119866 and the solution119891 are analytic functionsthe mixed derivatives are equivalent
We note that the derivatives function to119891 is unknown sowe suggest the following hypothesis
119891120578 = 1198911 = 119871minus1119866 [1198910 (120578)] 119891120578120578 = 1198912 = 119871minus11198661015840 [1198910 (120578)]

on 119891(120578) and 1198911015840(120578) but the point of intersection ofthe curves 1198911015840(120578) is 120578 = 04 Figure 7 demonstratesthe effects of Casson fluid parameter 120574 for axial andradial velocity it was also noted from this figurethat the increasing of 120574 causes increasing of 119891(120578)Subsequently the movement of the curves of 119891(120578)occurs from the bottom plate across the top plate dueto an increase of 120574 for 0 lt 120578 lt 1 whereas thesame situation of 1198911015840(120578) occurs when 120578 le 04 and thereverse case of their curves occurs when 04 lt 120578 le 1
From the above two cases it can be seen that the curves of119891(120578) and 1198911015840(120578) are different in distance between them wherein 119878 gt 0 it is wide then 119878 lt 0 However they have thesame behavior Moreover the bifurcation of 1198911015840(120578) in 119878 gt 0happened when 120578 = 05 and for 119878 lt 0 happened when120578 = 04 Generally it seems that the curve of119891(120578) is increasingwith increasing of 120578 for all values of 119878 119872 and 120574 while thecurve of 1198911015840(120578) is decreasing with increasing of 120578 for all abovevalues As for the effects of different physical parameters (thesqueezing number 119878 Casson fluid parameter 120574 the magneticnumber 119872) and the values 120572 119897 on the velocity components119906(119909 119910 119905) V(119909 119910 119905) and the vorticity 120596(119909 119910 119905) the followingcan be concluded
(i) In the case that the physical parameters and the values120572 119897 are constants (when there is a change in thesqueezing number) the surfaces are almost identical
except for the surface V(119909 119910 119905) This case shows aslight change which is a little curvature as indicatedin Figures 8 and 9 However there is a change in thesurfaces when 120572 lt 0 and 119878 ge 11 with a change inthe surface of119908(119909 119910 119905) while the surfaces of 119906(119909 119910 119905)and V(119909 119910 119905) remain similar
(ii) There is no change of other fixations values on thesurfaces when a change happened in the parameter119872or 120574 as shown in Figures 10ndash14 But there is change inthe surfaces 119906(119909 119910 119905) 119908(119909 119910 119905) and V(119909 119910 119905) when120572 lt 0 119878 le minus14 119872 le 4 and 120574 ge 04 with observingthat the surface V(119909 119910 119905) simply changes when119872 = 4in Figure 11 and 120574 = 04 in Figure 14
(iii) All the physical parameters are constants except achange in their values 120572 even if they are positive ornegative Each value of 120572 shows that the surface isdifferent from the other values of 119906(119909 119910 119905) V(119909 119910 119905)and 120596(119909 119910 119905) It was also noticed that the surfaceV(119909 119910 119905) takes the negative values of 120572 inversely withthe surface V(119909 119910 119905) that has a positive value of 120572Thiscan be seen in Figures 15 and 16
(iv) Finally Figures 17ndash19 show that there is no changein other fixations values on the surfaces 119906(119909 119910 119905)120596(119909 119910 119905) and V(119909 119910 119905) when a change happened invalue 119897 But there is change in the surfaces when120572 lt 0 minus15 lt 119897 lt 15 for 119906(119909 119910 119905) 120596(119909 119910 119905)

Physically magneto field parameter 119872 is increased thisleads to stronger Lorentz force along the vertical directionwhich offers more resistance to the flowThe velocity profilesexponentially decay to zero at shorter distances when either119872 or 120574 is increased This indicates that increase in either119872 or 120574 leads to thinner boundary layer Casson fluid
between parallel plates is a non-Newtonian fluid and itsparameter 120574 corresponds to viscosity in Newtonian fluidThus the increasing of 120574 leads to increase of viscous forceand decrease of the velocity of fluid The squeezing number119878 includes the flow which results from a movement ofthe two parallel plates with a fluid apart The geometricexplanation can be summarized as the magnetic field isapplied to electrical conducting fluid which accompaniesan increase of 119878 leading to increase of the velocity of the

two-dimensional nonlinear squeezing flow between twoparallel plates successfully It has been found that the con-struction of the novel algorithm possessed good convergentseries and the convergence of the results is shown explicitlyGraphs and tables are presented to investigate the influence ofphysical parameters on the velocity Convergence analysis iscarried out to back up the validity of the novel algorithm andcheck its computational efficiency Analysis of the converge
confirms that the novel algorithm is an efficient techniqueas compared to other methods presented in this work Ascan be seen from the comparison the computational resultsof the present solution and the results of other solutionsare identical with 5 or 6 decimal places It is noted thata magnetic field is a control phenomenon in many flowsand it could be employed to normalize the flow behaviorMoreover a squeeze number plays an important role in these

3 The Basic Steps of the Novel Algorithm
This section describes how to obtain a novel algorithm tocalculate the coefficients of the power series solution result-ing from solving nonlinear ordinary differential equations
resulting from using transforms ((8)-(10)) to find analytical-approximate solution These coefficients are important basesto construct the solution formula therefore they can becomputed recursively by differentiationways To illustrate thecomputation of these coefficients and derivation of the novelalgorithm we summarized the detailed new outlook in thefollowing steps
Step 1 Consider the nonlinear differential equation as fol-lows
119867(119891 (120578) 1198911015840 (120578) 11989110158401015840 (120578) 119891101584010158401015840 (120578) 119891(119899minus1) (120578) 119891(119899) (120578))= 0 (16)
and integrating (16) with respect to 120578 on [0 120578] yields119891 (120578) = 119891 (0) + 1198911015840 (0) 120578 + 11989110158401015840 (0) 12057822

(17)
where
119866 [119891 (120578)]= 119867(119891 (120578) 1198911015840 (120578) 11989110158401015840 (120578) 119891(119899minus1) (120578))

119889119899minus1119866 (1198910 (120578))119889120578119899minus1 (19)

and substituting (20) in (17) we obtain
119891 (120578) = 1198910 + 1198911 + 1198912 + 1198913 + 1198914 + sdot sdot sdot (21)

We see that the calculations become more complicated in thesecond and third derivatives because of the numerous calcu-lations Consequently the systematic structure on calculationis extremely important Fortunately due to the assumptionthat the operator 119866 and the solution119891 are analytic functionsthe mixed derivatives are equivalent
We note that the derivatives function to119891 is unknown sowe suggest the following hypothesis
119891120578 = 1198911 = 119871minus1119866 [1198910 (120578)] 119891120578120578 = 1198912 = 119871minus11198661015840 [1198910 (120578)]

on 119891(120578) and 1198911015840(120578) but the point of intersection ofthe curves 1198911015840(120578) is 120578 = 04 Figure 7 demonstratesthe effects of Casson fluid parameter 120574 for axial andradial velocity it was also noted from this figurethat the increasing of 120574 causes increasing of 119891(120578)Subsequently the movement of the curves of 119891(120578)occurs from the bottom plate across the top plate dueto an increase of 120574 for 0 lt 120578 lt 1 whereas thesame situation of 1198911015840(120578) occurs when 120578 le 04 and thereverse case of their curves occurs when 04 lt 120578 le 1
From the above two cases it can be seen that the curves of119891(120578) and 1198911015840(120578) are different in distance between them wherein 119878 gt 0 it is wide then 119878 lt 0 However they have thesame behavior Moreover the bifurcation of 1198911015840(120578) in 119878 gt 0happened when 120578 = 05 and for 119878 lt 0 happened when120578 = 04 Generally it seems that the curve of119891(120578) is increasingwith increasing of 120578 for all values of 119878 119872 and 120574 while thecurve of 1198911015840(120578) is decreasing with increasing of 120578 for all abovevalues As for the effects of different physical parameters (thesqueezing number 119878 Casson fluid parameter 120574 the magneticnumber 119872) and the values 120572 119897 on the velocity components119906(119909 119910 119905) V(119909 119910 119905) and the vorticity 120596(119909 119910 119905) the followingcan be concluded
(i) In the case that the physical parameters and the values120572 119897 are constants (when there is a change in thesqueezing number) the surfaces are almost identical
except for the surface V(119909 119910 119905) This case shows aslight change which is a little curvature as indicatedin Figures 8 and 9 However there is a change in thesurfaces when 120572 lt 0 and 119878 ge 11 with a change inthe surface of119908(119909 119910 119905) while the surfaces of 119906(119909 119910 119905)and V(119909 119910 119905) remain similar
(ii) There is no change of other fixations values on thesurfaces when a change happened in the parameter119872or 120574 as shown in Figures 10ndash14 But there is change inthe surfaces 119906(119909 119910 119905) 119908(119909 119910 119905) and V(119909 119910 119905) when120572 lt 0 119878 le minus14 119872 le 4 and 120574 ge 04 with observingthat the surface V(119909 119910 119905) simply changes when119872 = 4in Figure 11 and 120574 = 04 in Figure 14
(iii) All the physical parameters are constants except achange in their values 120572 even if they are positive ornegative Each value of 120572 shows that the surface isdifferent from the other values of 119906(119909 119910 119905) V(119909 119910 119905)and 120596(119909 119910 119905) It was also noticed that the surfaceV(119909 119910 119905) takes the negative values of 120572 inversely withthe surface V(119909 119910 119905) that has a positive value of 120572Thiscan be seen in Figures 15 and 16
(iv) Finally Figures 17ndash19 show that there is no changein other fixations values on the surfaces 119906(119909 119910 119905)120596(119909 119910 119905) and V(119909 119910 119905) when a change happened invalue 119897 But there is change in the surfaces when120572 lt 0 minus15 lt 119897 lt 15 for 119906(119909 119910 119905) 120596(119909 119910 119905)

Physically magneto field parameter 119872 is increased thisleads to stronger Lorentz force along the vertical directionwhich offers more resistance to the flowThe velocity profilesexponentially decay to zero at shorter distances when either119872 or 120574 is increased This indicates that increase in either119872 or 120574 leads to thinner boundary layer Casson fluid
between parallel plates is a non-Newtonian fluid and itsparameter 120574 corresponds to viscosity in Newtonian fluidThus the increasing of 120574 leads to increase of viscous forceand decrease of the velocity of fluid The squeezing number119878 includes the flow which results from a movement ofthe two parallel plates with a fluid apart The geometricexplanation can be summarized as the magnetic field isapplied to electrical conducting fluid which accompaniesan increase of 119878 leading to increase of the velocity of the

two-dimensional nonlinear squeezing flow between twoparallel plates successfully It has been found that the con-struction of the novel algorithm possessed good convergentseries and the convergence of the results is shown explicitlyGraphs and tables are presented to investigate the influence ofphysical parameters on the velocity Convergence analysis iscarried out to back up the validity of the novel algorithm andcheck its computational efficiency Analysis of the converge
confirms that the novel algorithm is an efficient techniqueas compared to other methods presented in this work Ascan be seen from the comparison the computational resultsof the present solution and the results of other solutionsare identical with 5 or 6 decimal places It is noted thata magnetic field is a control phenomenon in many flowsand it could be employed to normalize the flow behaviorMoreover a squeeze number plays an important role in these

3 The Basic Steps of the Novel Algorithm
This section describes how to obtain a novel algorithm tocalculate the coefficients of the power series solution result-ing from solving nonlinear ordinary differential equations
resulting from using transforms ((8)-(10)) to find analytical-approximate solution These coefficients are important basesto construct the solution formula therefore they can becomputed recursively by differentiationways To illustrate thecomputation of these coefficients and derivation of the novelalgorithm we summarized the detailed new outlook in thefollowing steps

on 119891(120578) and 1198911015840(120578) but the point of intersection ofthe curves 1198911015840(120578) is 120578 = 04 Figure 7 demonstratesthe effects of Casson fluid parameter 120574 for axial andradial velocity it was also noted from this figurethat the increasing of 120574 causes increasing of 119891(120578)Subsequently the movement of the curves of 119891(120578)occurs from the bottom plate across the top plate dueto an increase of 120574 for 0 lt 120578 lt 1 whereas thesame situation of 1198911015840(120578) occurs when 120578 le 04 and thereverse case of their curves occurs when 04 lt 120578 le 1
From the above two cases it can be seen that the curves of119891(120578) and 1198911015840(120578) are different in distance between them wherein 119878 gt 0 it is wide then 119878 lt 0 However they have thesame behavior Moreover the bifurcation of 1198911015840(120578) in 119878 gt 0happened when 120578 = 05 and for 119878 lt 0 happened when120578 = 04 Generally it seems that the curve of119891(120578) is increasingwith increasing of 120578 for all values of 119878 119872 and 120574 while thecurve of 1198911015840(120578) is decreasing with increasing of 120578 for all abovevalues As for the effects of different physical parameters (thesqueezing number 119878 Casson fluid parameter 120574 the magneticnumber 119872) and the values 120572 119897 on the velocity components119906(119909 119910 119905) V(119909 119910 119905) and the vorticity 120596(119909 119910 119905) the followingcan be concluded
(i) In the case that the physical parameters and the values120572 119897 are constants (when there is a change in thesqueezing number) the surfaces are almost identical
except for the surface V(119909 119910 119905) This case shows aslight change which is a little curvature as indicatedin Figures 8 and 9 However there is a change in thesurfaces when 120572 lt 0 and 119878 ge 11 with a change inthe surface of119908(119909 119910 119905) while the surfaces of 119906(119909 119910 119905)and V(119909 119910 119905) remain similar
(ii) There is no change of other fixations values on thesurfaces when a change happened in the parameter119872or 120574 as shown in Figures 10ndash14 But there is change inthe surfaces 119906(119909 119910 119905) 119908(119909 119910 119905) and V(119909 119910 119905) when120572 lt 0 119878 le minus14 119872 le 4 and 120574 ge 04 with observingthat the surface V(119909 119910 119905) simply changes when119872 = 4in Figure 11 and 120574 = 04 in Figure 14
(iii) All the physical parameters are constants except achange in their values 120572 even if they are positive ornegative Each value of 120572 shows that the surface isdifferent from the other values of 119906(119909 119910 119905) V(119909 119910 119905)and 120596(119909 119910 119905) It was also noticed that the surfaceV(119909 119910 119905) takes the negative values of 120572 inversely withthe surface V(119909 119910 119905) that has a positive value of 120572Thiscan be seen in Figures 15 and 16
(iv) Finally Figures 17ndash19 show that there is no changein other fixations values on the surfaces 119906(119909 119910 119905)120596(119909 119910 119905) and V(119909 119910 119905) when a change happened invalue 119897 But there is change in the surfaces when120572 lt 0 minus15 lt 119897 lt 15 for 119906(119909 119910 119905) 120596(119909 119910 119905)

and V(119909 119910 119905) with noticing that the surface V(119909 119910 119905)slightly changes when 119897 = 1 in Figure 18
Physically magneto field parameter 119872 is increased thisleads to stronger Lorentz force along the vertical directionwhich offers more resistance to the flowThe velocity profilesexponentially decay to zero at shorter distances when either119872 or 120574 is increased This indicates that increase in either119872 or 120574 leads to thinner boundary layer Casson fluid
between parallel plates is a non-Newtonian fluid and itsparameter 120574 corresponds to viscosity in Newtonian fluidThus the increasing of 120574 leads to increase of viscous forceand decrease of the velocity of fluid The squeezing number119878 includes the flow which results from a movement ofthe two parallel plates with a fluid apart The geometricexplanation can be summarized as the magnetic field isapplied to electrical conducting fluid which accompaniesan increase of 119878 leading to increase of the velocity of the

two-dimensional nonlinear squeezing flow between twoparallel plates successfully It has been found that the con-struction of the novel algorithm possessed good convergentseries and the convergence of the results is shown explicitlyGraphs and tables are presented to investigate the influence ofphysical parameters on the velocity Convergence analysis iscarried out to back up the validity of the novel algorithm andcheck its computational efficiency Analysis of the converge
confirms that the novel algorithm is an efficient techniqueas compared to other methods presented in this work Ascan be seen from the comparison the computational resultsof the present solution and the results of other solutionsare identical with 5 or 6 decimal places It is noted thata magnetic field is a control phenomenon in many flowsand it could be employed to normalize the flow behaviorMoreover a squeeze number plays an important role in these

We see that the calculations become more complicated in thesecond and third derivatives because of the numerous calcu-lations Consequently the systematic structure on calculationis extremely important Fortunately due to the assumptionthat the operator 119866 and the solution119891 are analytic functionsthe mixed derivatives are equivalent
We note that the derivatives function to119891 is unknown sowe suggest the following hypothesis
119891120578 = 1198911 = 119871minus1119866 [1198910 (120578)] 119891120578120578 = 1198912 = 119871minus11198661015840 [1198910 (120578)]

on 119891(120578) and 1198911015840(120578) but the point of intersection ofthe curves 1198911015840(120578) is 120578 = 04 Figure 7 demonstratesthe effects of Casson fluid parameter 120574 for axial andradial velocity it was also noted from this figurethat the increasing of 120574 causes increasing of 119891(120578)Subsequently the movement of the curves of 119891(120578)occurs from the bottom plate across the top plate dueto an increase of 120574 for 0 lt 120578 lt 1 whereas thesame situation of 1198911015840(120578) occurs when 120578 le 04 and thereverse case of their curves occurs when 04 lt 120578 le 1
From the above two cases it can be seen that the curves of119891(120578) and 1198911015840(120578) are different in distance between them wherein 119878 gt 0 it is wide then 119878 lt 0 However they have thesame behavior Moreover the bifurcation of 1198911015840(120578) in 119878 gt 0happened when 120578 = 05 and for 119878 lt 0 happened when120578 = 04 Generally it seems that the curve of119891(120578) is increasingwith increasing of 120578 for all values of 119878 119872 and 120574 while thecurve of 1198911015840(120578) is decreasing with increasing of 120578 for all abovevalues As for the effects of different physical parameters (thesqueezing number 119878 Casson fluid parameter 120574 the magneticnumber 119872) and the values 120572 119897 on the velocity components119906(119909 119910 119905) V(119909 119910 119905) and the vorticity 120596(119909 119910 119905) the followingcan be concluded
(i) In the case that the physical parameters and the values120572 119897 are constants (when there is a change in thesqueezing number) the surfaces are almost identical
except for the surface V(119909 119910 119905) This case shows aslight change which is a little curvature as indicatedin Figures 8 and 9 However there is a change in thesurfaces when 120572 lt 0 and 119878 ge 11 with a change inthe surface of119908(119909 119910 119905) while the surfaces of 119906(119909 119910 119905)and V(119909 119910 119905) remain similar
(ii) There is no change of other fixations values on thesurfaces when a change happened in the parameter119872or 120574 as shown in Figures 10ndash14 But there is change inthe surfaces 119906(119909 119910 119905) 119908(119909 119910 119905) and V(119909 119910 119905) when120572 lt 0 119878 le minus14 119872 le 4 and 120574 ge 04 with observingthat the surface V(119909 119910 119905) simply changes when119872 = 4in Figure 11 and 120574 = 04 in Figure 14
(iii) All the physical parameters are constants except achange in their values 120572 even if they are positive ornegative Each value of 120572 shows that the surface isdifferent from the other values of 119906(119909 119910 119905) V(119909 119910 119905)and 120596(119909 119910 119905) It was also noticed that the surfaceV(119909 119910 119905) takes the negative values of 120572 inversely withthe surface V(119909 119910 119905) that has a positive value of 120572Thiscan be seen in Figures 15 and 16
(iv) Finally Figures 17ndash19 show that there is no changein other fixations values on the surfaces 119906(119909 119910 119905)120596(119909 119910 119905) and V(119909 119910 119905) when a change happened invalue 119897 But there is change in the surfaces when120572 lt 0 minus15 lt 119897 lt 15 for 119906(119909 119910 119905) 120596(119909 119910 119905)

and V(119909 119910 119905) with noticing that the surface V(119909 119910 119905)slightly changes when 119897 = 1 in Figure 18
Physically magneto field parameter 119872 is increased thisleads to stronger Lorentz force along the vertical directionwhich offers more resistance to the flowThe velocity profilesexponentially decay to zero at shorter distances when either119872 or 120574 is increased This indicates that increase in either119872 or 120574 leads to thinner boundary layer Casson fluid
between parallel plates is a non-Newtonian fluid and itsparameter 120574 corresponds to viscosity in Newtonian fluidThus the increasing of 120574 leads to increase of viscous forceand decrease of the velocity of fluid The squeezing number119878 includes the flow which results from a movement ofthe two parallel plates with a fluid apart The geometricexplanation can be summarized as the magnetic field isapplied to electrical conducting fluid which accompaniesan increase of 119878 leading to increase of the velocity of the

two-dimensional nonlinear squeezing flow between twoparallel plates successfully It has been found that the con-struction of the novel algorithm possessed good convergentseries and the convergence of the results is shown explicitlyGraphs and tables are presented to investigate the influence ofphysical parameters on the velocity Convergence analysis iscarried out to back up the validity of the novel algorithm andcheck its computational efficiency Analysis of the converge
confirms that the novel algorithm is an efficient techniqueas compared to other methods presented in this work Ascan be seen from the comparison the computational resultsof the present solution and the results of other solutionsare identical with 5 or 6 decimal places It is noted thata magnetic field is a control phenomenon in many flowsand it could be employed to normalize the flow behaviorMoreover a squeeze number plays an important role in these

on 119891(120578) and 1198911015840(120578) but the point of intersection ofthe curves 1198911015840(120578) is 120578 = 04 Figure 7 demonstratesthe effects of Casson fluid parameter 120574 for axial andradial velocity it was also noted from this figurethat the increasing of 120574 causes increasing of 119891(120578)Subsequently the movement of the curves of 119891(120578)occurs from the bottom plate across the top plate dueto an increase of 120574 for 0 lt 120578 lt 1 whereas thesame situation of 1198911015840(120578) occurs when 120578 le 04 and thereverse case of their curves occurs when 04 lt 120578 le 1
From the above two cases it can be seen that the curves of119891(120578) and 1198911015840(120578) are different in distance between them wherein 119878 gt 0 it is wide then 119878 lt 0 However they have thesame behavior Moreover the bifurcation of 1198911015840(120578) in 119878 gt 0happened when 120578 = 05 and for 119878 lt 0 happened when120578 = 04 Generally it seems that the curve of119891(120578) is increasingwith increasing of 120578 for all values of 119878 119872 and 120574 while thecurve of 1198911015840(120578) is decreasing with increasing of 120578 for all abovevalues As for the effects of different physical parameters (thesqueezing number 119878 Casson fluid parameter 120574 the magneticnumber 119872) and the values 120572 119897 on the velocity components119906(119909 119910 119905) V(119909 119910 119905) and the vorticity 120596(119909 119910 119905) the followingcan be concluded
(i) In the case that the physical parameters and the values120572 119897 are constants (when there is a change in thesqueezing number) the surfaces are almost identical
except for the surface V(119909 119910 119905) This case shows aslight change which is a little curvature as indicatedin Figures 8 and 9 However there is a change in thesurfaces when 120572 lt 0 and 119878 ge 11 with a change inthe surface of119908(119909 119910 119905) while the surfaces of 119906(119909 119910 119905)and V(119909 119910 119905) remain similar
(ii) There is no change of other fixations values on thesurfaces when a change happened in the parameter119872or 120574 as shown in Figures 10ndash14 But there is change inthe surfaces 119906(119909 119910 119905) 119908(119909 119910 119905) and V(119909 119910 119905) when120572 lt 0 119878 le minus14 119872 le 4 and 120574 ge 04 with observingthat the surface V(119909 119910 119905) simply changes when119872 = 4in Figure 11 and 120574 = 04 in Figure 14
(iii) All the physical parameters are constants except achange in their values 120572 even if they are positive ornegative Each value of 120572 shows that the surface isdifferent from the other values of 119906(119909 119910 119905) V(119909 119910 119905)and 120596(119909 119910 119905) It was also noticed that the surfaceV(119909 119910 119905) takes the negative values of 120572 inversely withthe surface V(119909 119910 119905) that has a positive value of 120572Thiscan be seen in Figures 15 and 16
(iv) Finally Figures 17ndash19 show that there is no changein other fixations values on the surfaces 119906(119909 119910 119905)120596(119909 119910 119905) and V(119909 119910 119905) when a change happened invalue 119897 But there is change in the surfaces when120572 lt 0 minus15 lt 119897 lt 15 for 119906(119909 119910 119905) 120596(119909 119910 119905)

and V(119909 119910 119905) with noticing that the surface V(119909 119910 119905)slightly changes when 119897 = 1 in Figure 18
Physically magneto field parameter 119872 is increased thisleads to stronger Lorentz force along the vertical directionwhich offers more resistance to the flowThe velocity profilesexponentially decay to zero at shorter distances when either119872 or 120574 is increased This indicates that increase in either119872 or 120574 leads to thinner boundary layer Casson fluid
between parallel plates is a non-Newtonian fluid and itsparameter 120574 corresponds to viscosity in Newtonian fluidThus the increasing of 120574 leads to increase of viscous forceand decrease of the velocity of fluid The squeezing number119878 includes the flow which results from a movement ofthe two parallel plates with a fluid apart The geometricexplanation can be summarized as the magnetic field isapplied to electrical conducting fluid which accompaniesan increase of 119878 leading to increase of the velocity of the

two-dimensional nonlinear squeezing flow between twoparallel plates successfully It has been found that the con-struction of the novel algorithm possessed good convergentseries and the convergence of the results is shown explicitlyGraphs and tables are presented to investigate the influence ofphysical parameters on the velocity Convergence analysis iscarried out to back up the validity of the novel algorithm andcheck its computational efficiency Analysis of the converge
confirms that the novel algorithm is an efficient techniqueas compared to other methods presented in this work Ascan be seen from the comparison the computational resultsof the present solution and the results of other solutionsare identical with 5 or 6 decimal places It is noted thata magnetic field is a control phenomenon in many flowsand it could be employed to normalize the flow behaviorMoreover a squeeze number plays an important role in these

(32)
and we rewrite (32) as follows
119891 (120578) = 1198601 + 1198602120578 + 1198603 12057822 + 1198604 1205783

where

From the boundary conditions (33) becomes

and from Step 2 we have

(36)
Step 3 yields

on 119891(120578) and 1198911015840(120578) but the point of intersection ofthe curves 1198911015840(120578) is 120578 = 04 Figure 7 demonstratesthe effects of Casson fluid parameter 120574 for axial andradial velocity it was also noted from this figurethat the increasing of 120574 causes increasing of 119891(120578)Subsequently the movement of the curves of 119891(120578)occurs from the bottom plate across the top plate dueto an increase of 120574 for 0 lt 120578 lt 1 whereas thesame situation of 1198911015840(120578) occurs when 120578 le 04 and thereverse case of their curves occurs when 04 lt 120578 le 1
From the above two cases it can be seen that the curves of119891(120578) and 1198911015840(120578) are different in distance between them wherein 119878 gt 0 it is wide then 119878 lt 0 However they have thesame behavior Moreover the bifurcation of 1198911015840(120578) in 119878 gt 0happened when 120578 = 05 and for 119878 lt 0 happened when120578 = 04 Generally it seems that the curve of119891(120578) is increasingwith increasing of 120578 for all values of 119878 119872 and 120574 while thecurve of 1198911015840(120578) is decreasing with increasing of 120578 for all abovevalues As for the effects of different physical parameters (thesqueezing number 119878 Casson fluid parameter 120574 the magneticnumber 119872) and the values 120572 119897 on the velocity components119906(119909 119910 119905) V(119909 119910 119905) and the vorticity 120596(119909 119910 119905) the followingcan be concluded
(i) In the case that the physical parameters and the values120572 119897 are constants (when there is a change in thesqueezing number) the surfaces are almost identical
except for the surface V(119909 119910 119905) This case shows aslight change which is a little curvature as indicatedin Figures 8 and 9 However there is a change in thesurfaces when 120572 lt 0 and 119878 ge 11 with a change inthe surface of119908(119909 119910 119905) while the surfaces of 119906(119909 119910 119905)and V(119909 119910 119905) remain similar
(ii) There is no change of other fixations values on thesurfaces when a change happened in the parameter119872or 120574 as shown in Figures 10ndash14 But there is change inthe surfaces 119906(119909 119910 119905) 119908(119909 119910 119905) and V(119909 119910 119905) when120572 lt 0 119878 le minus14 119872 le 4 and 120574 ge 04 with observingthat the surface V(119909 119910 119905) simply changes when119872 = 4in Figure 11 and 120574 = 04 in Figure 14
(iii) All the physical parameters are constants except achange in their values 120572 even if they are positive ornegative Each value of 120572 shows that the surface isdifferent from the other values of 119906(119909 119910 119905) V(119909 119910 119905)and 120596(119909 119910 119905) It was also noticed that the surfaceV(119909 119910 119905) takes the negative values of 120572 inversely withthe surface V(119909 119910 119905) that has a positive value of 120572Thiscan be seen in Figures 15 and 16
(iv) Finally Figures 17ndash19 show that there is no changein other fixations values on the surfaces 119906(119909 119910 119905)120596(119909 119910 119905) and V(119909 119910 119905) when a change happened invalue 119897 But there is change in the surfaces when120572 lt 0 minus15 lt 119897 lt 15 for 119906(119909 119910 119905) 120596(119909 119910 119905)

Physically magneto field parameter 119872 is increased thisleads to stronger Lorentz force along the vertical directionwhich offers more resistance to the flowThe velocity profilesexponentially decay to zero at shorter distances when either119872 or 120574 is increased This indicates that increase in either119872 or 120574 leads to thinner boundary layer Casson fluid
between parallel plates is a non-Newtonian fluid and itsparameter 120574 corresponds to viscosity in Newtonian fluidThus the increasing of 120574 leads to increase of viscous forceand decrease of the velocity of fluid The squeezing number119878 includes the flow which results from a movement ofthe two parallel plates with a fluid apart The geometricexplanation can be summarized as the magnetic field isapplied to electrical conducting fluid which accompaniesan increase of 119878 leading to increase of the velocity of the

two-dimensional nonlinear squeezing flow between twoparallel plates successfully It has been found that the con-struction of the novel algorithm possessed good convergentseries and the convergence of the results is shown explicitlyGraphs and tables are presented to investigate the influence ofphysical parameters on the velocity Convergence analysis iscarried out to back up the validity of the novel algorithm andcheck its computational efficiency Analysis of the converge
confirms that the novel algorithm is an efficient techniqueas compared to other methods presented in this work Ascan be seen from the comparison the computational resultsof the present solution and the results of other solutionsare identical with 5 or 6 decimal places It is noted thata magnetic field is a control phenomenon in many flowsand it could be employed to normalize the flow behaviorMoreover a squeeze number plays an important role in these

on 119891(120578) and 1198911015840(120578) but the point of intersection ofthe curves 1198911015840(120578) is 120578 = 04 Figure 7 demonstratesthe effects of Casson fluid parameter 120574 for axial andradial velocity it was also noted from this figurethat the increasing of 120574 causes increasing of 119891(120578)Subsequently the movement of the curves of 119891(120578)occurs from the bottom plate across the top plate dueto an increase of 120574 for 0 lt 120578 lt 1 whereas thesame situation of 1198911015840(120578) occurs when 120578 le 04 and thereverse case of their curves occurs when 04 lt 120578 le 1
From the above two cases it can be seen that the curves of119891(120578) and 1198911015840(120578) are different in distance between them wherein 119878 gt 0 it is wide then 119878 lt 0 However they have thesame behavior Moreover the bifurcation of 1198911015840(120578) in 119878 gt 0happened when 120578 = 05 and for 119878 lt 0 happened when120578 = 04 Generally it seems that the curve of119891(120578) is increasingwith increasing of 120578 for all values of 119878 119872 and 120574 while thecurve of 1198911015840(120578) is decreasing with increasing of 120578 for all abovevalues As for the effects of different physical parameters (thesqueezing number 119878 Casson fluid parameter 120574 the magneticnumber 119872) and the values 120572 119897 on the velocity components119906(119909 119910 119905) V(119909 119910 119905) and the vorticity 120596(119909 119910 119905) the followingcan be concluded
(i) In the case that the physical parameters and the values120572 119897 are constants (when there is a change in thesqueezing number) the surfaces are almost identical
except for the surface V(119909 119910 119905) This case shows aslight change which is a little curvature as indicatedin Figures 8 and 9 However there is a change in thesurfaces when 120572 lt 0 and 119878 ge 11 with a change inthe surface of119908(119909 119910 119905) while the surfaces of 119906(119909 119910 119905)and V(119909 119910 119905) remain similar
(ii) There is no change of other fixations values on thesurfaces when a change happened in the parameter119872or 120574 as shown in Figures 10ndash14 But there is change inthe surfaces 119906(119909 119910 119905) 119908(119909 119910 119905) and V(119909 119910 119905) when120572 lt 0 119878 le minus14 119872 le 4 and 120574 ge 04 with observingthat the surface V(119909 119910 119905) simply changes when119872 = 4in Figure 11 and 120574 = 04 in Figure 14
(iii) All the physical parameters are constants except achange in their values 120572 even if they are positive ornegative Each value of 120572 shows that the surface isdifferent from the other values of 119906(119909 119910 119905) V(119909 119910 119905)and 120596(119909 119910 119905) It was also noticed that the surfaceV(119909 119910 119905) takes the negative values of 120572 inversely withthe surface V(119909 119910 119905) that has a positive value of 120572Thiscan be seen in Figures 15 and 16
(iv) Finally Figures 17ndash19 show that there is no changein other fixations values on the surfaces 119906(119909 119910 119905)120596(119909 119910 119905) and V(119909 119910 119905) when a change happened invalue 119897 But there is change in the surfaces when120572 lt 0 minus15 lt 119897 lt 15 for 119906(119909 119910 119905) 120596(119909 119910 119905)

and V(119909 119910 119905) with noticing that the surface V(119909 119910 119905)slightly changes when 119897 = 1 in Figure 18
Physically magneto field parameter 119872 is increased thisleads to stronger Lorentz force along the vertical directionwhich offers more resistance to the flowThe velocity profilesexponentially decay to zero at shorter distances when either119872 or 120574 is increased This indicates that increase in either119872 or 120574 leads to thinner boundary layer Casson fluid
between parallel plates is a non-Newtonian fluid and itsparameter 120574 corresponds to viscosity in Newtonian fluidThus the increasing of 120574 leads to increase of viscous forceand decrease of the velocity of fluid The squeezing number119878 includes the flow which results from a movement ofthe two parallel plates with a fluid apart The geometricexplanation can be summarized as the magnetic field isapplied to electrical conducting fluid which accompaniesan increase of 119878 leading to increase of the velocity of the

two-dimensional nonlinear squeezing flow between twoparallel plates successfully It has been found that the con-struction of the novel algorithm possessed good convergentseries and the convergence of the results is shown explicitlyGraphs and tables are presented to investigate the influence ofphysical parameters on the velocity Convergence analysis iscarried out to back up the validity of the novel algorithm andcheck its computational efficiency Analysis of the converge
confirms that the novel algorithm is an efficient techniqueas compared to other methods presented in this work Ascan be seen from the comparison the computational resultsof the present solution and the results of other solutionsare identical with 5 or 6 decimal places It is noted thata magnetic field is a control phenomenon in many flowsand it could be employed to normalize the flow behaviorMoreover a squeeze number plays an important role in these

on 119891(120578) and 1198911015840(120578) but the point of intersection ofthe curves 1198911015840(120578) is 120578 = 04 Figure 7 demonstratesthe effects of Casson fluid parameter 120574 for axial andradial velocity it was also noted from this figurethat the increasing of 120574 causes increasing of 119891(120578)Subsequently the movement of the curves of 119891(120578)occurs from the bottom plate across the top plate dueto an increase of 120574 for 0 lt 120578 lt 1 whereas thesame situation of 1198911015840(120578) occurs when 120578 le 04 and thereverse case of their curves occurs when 04 lt 120578 le 1
From the above two cases it can be seen that the curves of119891(120578) and 1198911015840(120578) are different in distance between them wherein 119878 gt 0 it is wide then 119878 lt 0 However they have thesame behavior Moreover the bifurcation of 1198911015840(120578) in 119878 gt 0happened when 120578 = 05 and for 119878 lt 0 happened when120578 = 04 Generally it seems that the curve of119891(120578) is increasingwith increasing of 120578 for all values of 119878 119872 and 120574 while thecurve of 1198911015840(120578) is decreasing with increasing of 120578 for all abovevalues As for the effects of different physical parameters (thesqueezing number 119878 Casson fluid parameter 120574 the magneticnumber 119872) and the values 120572 119897 on the velocity components119906(119909 119910 119905) V(119909 119910 119905) and the vorticity 120596(119909 119910 119905) the followingcan be concluded
(i) In the case that the physical parameters and the values120572 119897 are constants (when there is a change in thesqueezing number) the surfaces are almost identical
except for the surface V(119909 119910 119905) This case shows aslight change which is a little curvature as indicatedin Figures 8 and 9 However there is a change in thesurfaces when 120572 lt 0 and 119878 ge 11 with a change inthe surface of119908(119909 119910 119905) while the surfaces of 119906(119909 119910 119905)and V(119909 119910 119905) remain similar
(ii) There is no change of other fixations values on thesurfaces when a change happened in the parameter119872or 120574 as shown in Figures 10ndash14 But there is change inthe surfaces 119906(119909 119910 119905) 119908(119909 119910 119905) and V(119909 119910 119905) when120572 lt 0 119878 le minus14 119872 le 4 and 120574 ge 04 with observingthat the surface V(119909 119910 119905) simply changes when119872 = 4in Figure 11 and 120574 = 04 in Figure 14
(iii) All the physical parameters are constants except achange in their values 120572 even if they are positive ornegative Each value of 120572 shows that the surface isdifferent from the other values of 119906(119909 119910 119905) V(119909 119910 119905)and 120596(119909 119910 119905) It was also noticed that the surfaceV(119909 119910 119905) takes the negative values of 120572 inversely withthe surface V(119909 119910 119905) that has a positive value of 120572Thiscan be seen in Figures 15 and 16
(iv) Finally Figures 17ndash19 show that there is no changein other fixations values on the surfaces 119906(119909 119910 119905)120596(119909 119910 119905) and V(119909 119910 119905) when a change happened invalue 119897 But there is change in the surfaces when120572 lt 0 minus15 lt 119897 lt 15 for 119906(119909 119910 119905) 120596(119909 119910 119905)

and V(119909 119910 119905) with noticing that the surface V(119909 119910 119905)slightly changes when 119897 = 1 in Figure 18
Physically magneto field parameter 119872 is increased thisleads to stronger Lorentz force along the vertical directionwhich offers more resistance to the flowThe velocity profilesexponentially decay to zero at shorter distances when either119872 or 120574 is increased This indicates that increase in either119872 or 120574 leads to thinner boundary layer Casson fluid
between parallel plates is a non-Newtonian fluid and itsparameter 120574 corresponds to viscosity in Newtonian fluidThus the increasing of 120574 leads to increase of viscous forceand decrease of the velocity of fluid The squeezing number119878 includes the flow which results from a movement ofthe two parallel plates with a fluid apart The geometricexplanation can be summarized as the magnetic field isapplied to electrical conducting fluid which accompaniesan increase of 119878 leading to increase of the velocity of the

two-dimensional nonlinear squeezing flow between twoparallel plates successfully It has been found that the con-struction of the novel algorithm possessed good convergentseries and the convergence of the results is shown explicitlyGraphs and tables are presented to investigate the influence ofphysical parameters on the velocity Convergence analysis iscarried out to back up the validity of the novel algorithm andcheck its computational efficiency Analysis of the converge
confirms that the novel algorithm is an efficient techniqueas compared to other methods presented in this work Ascan be seen from the comparison the computational resultsof the present solution and the results of other solutionsare identical with 5 or 6 decimal places It is noted thata magnetic field is a control phenomenon in many flowsand it could be employed to normalize the flow behaviorMoreover a squeeze number plays an important role in these

on 119891(120578) and 1198911015840(120578) but the point of intersection ofthe curves 1198911015840(120578) is 120578 = 04 Figure 7 demonstratesthe effects of Casson fluid parameter 120574 for axial andradial velocity it was also noted from this figurethat the increasing of 120574 causes increasing of 119891(120578)Subsequently the movement of the curves of 119891(120578)occurs from the bottom plate across the top plate dueto an increase of 120574 for 0 lt 120578 lt 1 whereas thesame situation of 1198911015840(120578) occurs when 120578 le 04 and thereverse case of their curves occurs when 04 lt 120578 le 1
From the above two cases it can be seen that the curves of119891(120578) and 1198911015840(120578) are different in distance between them wherein 119878 gt 0 it is wide then 119878 lt 0 However they have thesame behavior Moreover the bifurcation of 1198911015840(120578) in 119878 gt 0happened when 120578 = 05 and for 119878 lt 0 happened when120578 = 04 Generally it seems that the curve of119891(120578) is increasingwith increasing of 120578 for all values of 119878 119872 and 120574 while thecurve of 1198911015840(120578) is decreasing with increasing of 120578 for all abovevalues As for the effects of different physical parameters (thesqueezing number 119878 Casson fluid parameter 120574 the magneticnumber 119872) and the values 120572 119897 on the velocity components119906(119909 119910 119905) V(119909 119910 119905) and the vorticity 120596(119909 119910 119905) the followingcan be concluded
(i) In the case that the physical parameters and the values120572 119897 are constants (when there is a change in thesqueezing number) the surfaces are almost identical
except for the surface V(119909 119910 119905) This case shows aslight change which is a little curvature as indicatedin Figures 8 and 9 However there is a change in thesurfaces when 120572 lt 0 and 119878 ge 11 with a change inthe surface of119908(119909 119910 119905) while the surfaces of 119906(119909 119910 119905)and V(119909 119910 119905) remain similar
(ii) There is no change of other fixations values on thesurfaces when a change happened in the parameter119872or 120574 as shown in Figures 10ndash14 But there is change inthe surfaces 119906(119909 119910 119905) 119908(119909 119910 119905) and V(119909 119910 119905) when120572 lt 0 119878 le minus14 119872 le 4 and 120574 ge 04 with observingthat the surface V(119909 119910 119905) simply changes when119872 = 4in Figure 11 and 120574 = 04 in Figure 14
(iii) All the physical parameters are constants except achange in their values 120572 even if they are positive ornegative Each value of 120572 shows that the surface isdifferent from the other values of 119906(119909 119910 119905) V(119909 119910 119905)and 120596(119909 119910 119905) It was also noticed that the surfaceV(119909 119910 119905) takes the negative values of 120572 inversely withthe surface V(119909 119910 119905) that has a positive value of 120572Thiscan be seen in Figures 15 and 16
(iv) Finally Figures 17ndash19 show that there is no changein other fixations values on the surfaces 119906(119909 119910 119905)120596(119909 119910 119905) and V(119909 119910 119905) when a change happened invalue 119897 But there is change in the surfaces when120572 lt 0 minus15 lt 119897 lt 15 for 119906(119909 119910 119905) 120596(119909 119910 119905)

and V(119909 119910 119905) with noticing that the surface V(119909 119910 119905)slightly changes when 119897 = 1 in Figure 18
Physically magneto field parameter 119872 is increased thisleads to stronger Lorentz force along the vertical directionwhich offers more resistance to the flowThe velocity profilesexponentially decay to zero at shorter distances when either119872 or 120574 is increased This indicates that increase in either119872 or 120574 leads to thinner boundary layer Casson fluid
between parallel plates is a non-Newtonian fluid and itsparameter 120574 corresponds to viscosity in Newtonian fluidThus the increasing of 120574 leads to increase of viscous forceand decrease of the velocity of fluid The squeezing number119878 includes the flow which results from a movement ofthe two parallel plates with a fluid apart The geometricexplanation can be summarized as the magnetic field isapplied to electrical conducting fluid which accompaniesan increase of 119878 leading to increase of the velocity of the

two-dimensional nonlinear squeezing flow between twoparallel plates successfully It has been found that the con-struction of the novel algorithm possessed good convergentseries and the convergence of the results is shown explicitlyGraphs and tables are presented to investigate the influence ofphysical parameters on the velocity Convergence analysis iscarried out to back up the validity of the novel algorithm andcheck its computational efficiency Analysis of the converge
confirms that the novel algorithm is an efficient techniqueas compared to other methods presented in this work Ascan be seen from the comparison the computational resultsof the present solution and the results of other solutionsare identical with 5 or 6 decimal places It is noted thata magnetic field is a control phenomenon in many flowsand it could be employed to normalize the flow behaviorMoreover a squeeze number plays an important role in these

on 119891(120578) and 1198911015840(120578) but the point of intersection ofthe curves 1198911015840(120578) is 120578 = 04 Figure 7 demonstratesthe effects of Casson fluid parameter 120574 for axial andradial velocity it was also noted from this figurethat the increasing of 120574 causes increasing of 119891(120578)Subsequently the movement of the curves of 119891(120578)occurs from the bottom plate across the top plate dueto an increase of 120574 for 0 lt 120578 lt 1 whereas thesame situation of 1198911015840(120578) occurs when 120578 le 04 and thereverse case of their curves occurs when 04 lt 120578 le 1
From the above two cases it can be seen that the curves of119891(120578) and 1198911015840(120578) are different in distance between them wherein 119878 gt 0 it is wide then 119878 lt 0 However they have thesame behavior Moreover the bifurcation of 1198911015840(120578) in 119878 gt 0happened when 120578 = 05 and for 119878 lt 0 happened when120578 = 04 Generally it seems that the curve of119891(120578) is increasingwith increasing of 120578 for all values of 119878 119872 and 120574 while thecurve of 1198911015840(120578) is decreasing with increasing of 120578 for all abovevalues As for the effects of different physical parameters (thesqueezing number 119878 Casson fluid parameter 120574 the magneticnumber 119872) and the values 120572 119897 on the velocity components119906(119909 119910 119905) V(119909 119910 119905) and the vorticity 120596(119909 119910 119905) the followingcan be concluded
(i) In the case that the physical parameters and the values120572 119897 are constants (when there is a change in thesqueezing number) the surfaces are almost identical
except for the surface V(119909 119910 119905) This case shows aslight change which is a little curvature as indicatedin Figures 8 and 9 However there is a change in thesurfaces when 120572 lt 0 and 119878 ge 11 with a change inthe surface of119908(119909 119910 119905) while the surfaces of 119906(119909 119910 119905)and V(119909 119910 119905) remain similar
(ii) There is no change of other fixations values on thesurfaces when a change happened in the parameter119872or 120574 as shown in Figures 10ndash14 But there is change inthe surfaces 119906(119909 119910 119905) 119908(119909 119910 119905) and V(119909 119910 119905) when120572 lt 0 119878 le minus14 119872 le 4 and 120574 ge 04 with observingthat the surface V(119909 119910 119905) simply changes when119872 = 4in Figure 11 and 120574 = 04 in Figure 14
(iii) All the physical parameters are constants except achange in their values 120572 even if they are positive ornegative Each value of 120572 shows that the surface isdifferent from the other values of 119906(119909 119910 119905) V(119909 119910 119905)and 120596(119909 119910 119905) It was also noticed that the surfaceV(119909 119910 119905) takes the negative values of 120572 inversely withthe surface V(119909 119910 119905) that has a positive value of 120572Thiscan be seen in Figures 15 and 16
(iv) Finally Figures 17ndash19 show that there is no changein other fixations values on the surfaces 119906(119909 119910 119905)120596(119909 119910 119905) and V(119909 119910 119905) when a change happened invalue 119897 But there is change in the surfaces when120572 lt 0 minus15 lt 119897 lt 15 for 119906(119909 119910 119905) 120596(119909 119910 119905)

and V(119909 119910 119905) with noticing that the surface V(119909 119910 119905)slightly changes when 119897 = 1 in Figure 18
Physically magneto field parameter 119872 is increased thisleads to stronger Lorentz force along the vertical directionwhich offers more resistance to the flowThe velocity profilesexponentially decay to zero at shorter distances when either119872 or 120574 is increased This indicates that increase in either119872 or 120574 leads to thinner boundary layer Casson fluid
between parallel plates is a non-Newtonian fluid and itsparameter 120574 corresponds to viscosity in Newtonian fluidThus the increasing of 120574 leads to increase of viscous forceand decrease of the velocity of fluid The squeezing number119878 includes the flow which results from a movement ofthe two parallel plates with a fluid apart The geometricexplanation can be summarized as the magnetic field isapplied to electrical conducting fluid which accompaniesan increase of 119878 leading to increase of the velocity of the

two-dimensional nonlinear squeezing flow between twoparallel plates successfully It has been found that the con-struction of the novel algorithm possessed good convergentseries and the convergence of the results is shown explicitlyGraphs and tables are presented to investigate the influence ofphysical parameters on the velocity Convergence analysis iscarried out to back up the validity of the novel algorithm andcheck its computational efficiency Analysis of the converge
confirms that the novel algorithm is an efficient techniqueas compared to other methods presented in this work Ascan be seen from the comparison the computational resultsof the present solution and the results of other solutionsare identical with 5 or 6 decimal places It is noted thata magnetic field is a control phenomenon in many flowsand it could be employed to normalize the flow behaviorMoreover a squeeze number plays an important role in these

on 119891(120578) and 1198911015840(120578) but the point of intersection ofthe curves 1198911015840(120578) is 120578 = 04 Figure 7 demonstratesthe effects of Casson fluid parameter 120574 for axial andradial velocity it was also noted from this figurethat the increasing of 120574 causes increasing of 119891(120578)Subsequently the movement of the curves of 119891(120578)occurs from the bottom plate across the top plate dueto an increase of 120574 for 0 lt 120578 lt 1 whereas thesame situation of 1198911015840(120578) occurs when 120578 le 04 and thereverse case of their curves occurs when 04 lt 120578 le 1
From the above two cases it can be seen that the curves of119891(120578) and 1198911015840(120578) are different in distance between them wherein 119878 gt 0 it is wide then 119878 lt 0 However they have thesame behavior Moreover the bifurcation of 1198911015840(120578) in 119878 gt 0happened when 120578 = 05 and for 119878 lt 0 happened when120578 = 04 Generally it seems that the curve of119891(120578) is increasingwith increasing of 120578 for all values of 119878 119872 and 120574 while thecurve of 1198911015840(120578) is decreasing with increasing of 120578 for all abovevalues As for the effects of different physical parameters (thesqueezing number 119878 Casson fluid parameter 120574 the magneticnumber 119872) and the values 120572 119897 on the velocity components119906(119909 119910 119905) V(119909 119910 119905) and the vorticity 120596(119909 119910 119905) the followingcan be concluded
(i) In the case that the physical parameters and the values120572 119897 are constants (when there is a change in thesqueezing number) the surfaces are almost identical
except for the surface V(119909 119910 119905) This case shows aslight change which is a little curvature as indicatedin Figures 8 and 9 However there is a change in thesurfaces when 120572 lt 0 and 119878 ge 11 with a change inthe surface of119908(119909 119910 119905) while the surfaces of 119906(119909 119910 119905)and V(119909 119910 119905) remain similar
(ii) There is no change of other fixations values on thesurfaces when a change happened in the parameter119872or 120574 as shown in Figures 10ndash14 But there is change inthe surfaces 119906(119909 119910 119905) 119908(119909 119910 119905) and V(119909 119910 119905) when120572 lt 0 119878 le minus14 119872 le 4 and 120574 ge 04 with observingthat the surface V(119909 119910 119905) simply changes when119872 = 4in Figure 11 and 120574 = 04 in Figure 14
(iii) All the physical parameters are constants except achange in their values 120572 even if they are positive ornegative Each value of 120572 shows that the surface isdifferent from the other values of 119906(119909 119910 119905) V(119909 119910 119905)and 120596(119909 119910 119905) It was also noticed that the surfaceV(119909 119910 119905) takes the negative values of 120572 inversely withthe surface V(119909 119910 119905) that has a positive value of 120572Thiscan be seen in Figures 15 and 16
(iv) Finally Figures 17ndash19 show that there is no changein other fixations values on the surfaces 119906(119909 119910 119905)120596(119909 119910 119905) and V(119909 119910 119905) when a change happened invalue 119897 But there is change in the surfaces when120572 lt 0 minus15 lt 119897 lt 15 for 119906(119909 119910 119905) 120596(119909 119910 119905)

and V(119909 119910 119905) with noticing that the surface V(119909 119910 119905)slightly changes when 119897 = 1 in Figure 18
Physically magneto field parameter 119872 is increased thisleads to stronger Lorentz force along the vertical directionwhich offers more resistance to the flowThe velocity profilesexponentially decay to zero at shorter distances when either119872 or 120574 is increased This indicates that increase in either119872 or 120574 leads to thinner boundary layer Casson fluid
between parallel plates is a non-Newtonian fluid and itsparameter 120574 corresponds to viscosity in Newtonian fluidThus the increasing of 120574 leads to increase of viscous forceand decrease of the velocity of fluid The squeezing number119878 includes the flow which results from a movement ofthe two parallel plates with a fluid apart The geometricexplanation can be summarized as the magnetic field isapplied to electrical conducting fluid which accompaniesan increase of 119878 leading to increase of the velocity of the

two-dimensional nonlinear squeezing flow between twoparallel plates successfully It has been found that the con-struction of the novel algorithm possessed good convergentseries and the convergence of the results is shown explicitlyGraphs and tables are presented to investigate the influence ofphysical parameters on the velocity Convergence analysis iscarried out to back up the validity of the novel algorithm andcheck its computational efficiency Analysis of the converge
confirms that the novel algorithm is an efficient techniqueas compared to other methods presented in this work Ascan be seen from the comparison the computational resultsof the present solution and the results of other solutionsare identical with 5 or 6 decimal places It is noted thata magnetic field is a control phenomenon in many flowsand it could be employed to normalize the flow behaviorMoreover a squeeze number plays an important role in these

on 119891(120578) and 1198911015840(120578) but the point of intersection ofthe curves 1198911015840(120578) is 120578 = 04 Figure 7 demonstratesthe effects of Casson fluid parameter 120574 for axial andradial velocity it was also noted from this figurethat the increasing of 120574 causes increasing of 119891(120578)Subsequently the movement of the curves of 119891(120578)occurs from the bottom plate across the top plate dueto an increase of 120574 for 0 lt 120578 lt 1 whereas thesame situation of 1198911015840(120578) occurs when 120578 le 04 and thereverse case of their curves occurs when 04 lt 120578 le 1
From the above two cases it can be seen that the curves of119891(120578) and 1198911015840(120578) are different in distance between them wherein 119878 gt 0 it is wide then 119878 lt 0 However they have thesame behavior Moreover the bifurcation of 1198911015840(120578) in 119878 gt 0happened when 120578 = 05 and for 119878 lt 0 happened when120578 = 04 Generally it seems that the curve of119891(120578) is increasingwith increasing of 120578 for all values of 119878 119872 and 120574 while thecurve of 1198911015840(120578) is decreasing with increasing of 120578 for all abovevalues As for the effects of different physical parameters (thesqueezing number 119878 Casson fluid parameter 120574 the magneticnumber 119872) and the values 120572 119897 on the velocity components119906(119909 119910 119905) V(119909 119910 119905) and the vorticity 120596(119909 119910 119905) the followingcan be concluded
(i) In the case that the physical parameters and the values120572 119897 are constants (when there is a change in thesqueezing number) the surfaces are almost identical
except for the surface V(119909 119910 119905) This case shows aslight change which is a little curvature as indicatedin Figures 8 and 9 However there is a change in thesurfaces when 120572 lt 0 and 119878 ge 11 with a change inthe surface of119908(119909 119910 119905) while the surfaces of 119906(119909 119910 119905)and V(119909 119910 119905) remain similar
(ii) There is no change of other fixations values on thesurfaces when a change happened in the parameter119872or 120574 as shown in Figures 10ndash14 But there is change inthe surfaces 119906(119909 119910 119905) 119908(119909 119910 119905) and V(119909 119910 119905) when120572 lt 0 119878 le minus14 119872 le 4 and 120574 ge 04 with observingthat the surface V(119909 119910 119905) simply changes when119872 = 4in Figure 11 and 120574 = 04 in Figure 14
(iii) All the physical parameters are constants except achange in their values 120572 even if they are positive ornegative Each value of 120572 shows that the surface isdifferent from the other values of 119906(119909 119910 119905) V(119909 119910 119905)and 120596(119909 119910 119905) It was also noticed that the surfaceV(119909 119910 119905) takes the negative values of 120572 inversely withthe surface V(119909 119910 119905) that has a positive value of 120572Thiscan be seen in Figures 15 and 16
(iv) Finally Figures 17ndash19 show that there is no changein other fixations values on the surfaces 119906(119909 119910 119905)120596(119909 119910 119905) and V(119909 119910 119905) when a change happened invalue 119897 But there is change in the surfaces when120572 lt 0 minus15 lt 119897 lt 15 for 119906(119909 119910 119905) 120596(119909 119910 119905)

Physically magneto field parameter 119872 is increased thisleads to stronger Lorentz force along the vertical directionwhich offers more resistance to the flowThe velocity profilesexponentially decay to zero at shorter distances when either119872 or 120574 is increased This indicates that increase in either119872 or 120574 leads to thinner boundary layer Casson fluid
between parallel plates is a non-Newtonian fluid and itsparameter 120574 corresponds to viscosity in Newtonian fluidThus the increasing of 120574 leads to increase of viscous forceand decrease of the velocity of fluid The squeezing number119878 includes the flow which results from a movement ofthe two parallel plates with a fluid apart The geometricexplanation can be summarized as the magnetic field isapplied to electrical conducting fluid which accompaniesan increase of 119878 leading to increase of the velocity of the

two-dimensional nonlinear squeezing flow between twoparallel plates successfully It has been found that the con-struction of the novel algorithm possessed good convergentseries and the convergence of the results is shown explicitlyGraphs and tables are presented to investigate the influence ofphysical parameters on the velocity Convergence analysis iscarried out to back up the validity of the novel algorithm andcheck its computational efficiency Analysis of the converge
confirms that the novel algorithm is an efficient techniqueas compared to other methods presented in this work Ascan be seen from the comparison the computational resultsof the present solution and the results of other solutionsare identical with 5 or 6 decimal places It is noted thata magnetic field is a control phenomenon in many flowsand it could be employed to normalize the flow behaviorMoreover a squeeze number plays an important role in these

Physically magneto field parameter 119872 is increased thisleads to stronger Lorentz force along the vertical directionwhich offers more resistance to the flowThe velocity profilesexponentially decay to zero at shorter distances when either119872 or 120574 is increased This indicates that increase in either119872 or 120574 leads to thinner boundary layer Casson fluid
between parallel plates is a non-Newtonian fluid and itsparameter 120574 corresponds to viscosity in Newtonian fluidThus the increasing of 120574 leads to increase of viscous forceand decrease of the velocity of fluid The squeezing number119878 includes the flow which results from a movement ofthe two parallel plates with a fluid apart The geometricexplanation can be summarized as the magnetic field isapplied to electrical conducting fluid which accompaniesan increase of 119878 leading to increase of the velocity of the

two-dimensional nonlinear squeezing flow between twoparallel plates successfully It has been found that the con-struction of the novel algorithm possessed good convergentseries and the convergence of the results is shown explicitlyGraphs and tables are presented to investigate the influence ofphysical parameters on the velocity Convergence analysis iscarried out to back up the validity of the novel algorithm andcheck its computational efficiency Analysis of the converge
confirms that the novel algorithm is an efficient techniqueas compared to other methods presented in this work Ascan be seen from the comparison the computational resultsof the present solution and the results of other solutionsare identical with 5 or 6 decimal places It is noted thata magnetic field is a control phenomenon in many flowsand it could be employed to normalize the flow behaviorMoreover a squeeze number plays an important role in these
