BIDIRECTIONAL FLOATING HYDRO TURBINE
PRESENTED BY
ADITYA A. PANCHAL
CONCEPT
“The FHT could be used to produce both wave energy and energy from tidal current at the same time. The turbine converts water power into rotational power at its shaft, which is then converted to electrical power by the dynamo.”
PRINCIPLE
It works on the principle of conversion of kinetic energy of water (wave) into electrical energy using dynamo and floating turbine.
PROBLEM DEFINITION
TO UTILISE TIDAL FLOW OF WATER BY CONVERTING ITS K.E. INTO WORK USING BIDIRECTIONAL FLOW TURBINE.
TO OVERCOME THE DEFECTS AND SAVE COST IN POWER GENERATION FROM OTHER CONVENTIONAL SOURCES OF HYROPOWER.
OBJECTIVES
Our main objective is to generate electricity from conventional resources [water] using bidirectional floating hydro turbine.
To study the principle of hydro turbine using suspension system

TURBINE BLADE FIBER REINFORED POLYMER
DYNAMO 12 WATTS
DESIGN OF TURBINE BLADE
Material- GFRP(Glass fiber Reinforce polymer)Thickness of blade material = 5mmCross section area of blade = 5 x 650 = 3250 mm
TURBINE BLADE CALCULATIONGFRP Glass fiber
reinforced polymer (60 vol% E-glass)
Density 2000 [kg.m-3]
Strength160 [N.mm-2]
We knowDrag force Fd = 0.5 x ρ x A x V2
Where,Air Density (ρ):- 1000 kg/m3
Area of turbine blade A in m2
Air velocity V in m/s
Fd = 0.5 x 1000 x 0.65 x 0.11 x 62
Fd = 1287 kg = 12870 N
Thickness of blade material = 5mmCross section area of blade = 5 x 650 = 3250 mmInduce stress Fc = F / A = 12870/ 3250 = 3.96 N / mm2
Allowable compressive stress for GFRP is 160 N / mm2
So selection of thickness of turbine blade is safe under given condition.
So torque on turbine blade = F x RR = (280 / 2) + (110/2 ) = 195 mmT = 12870 x 195 =2509 N m
Design of Turbine
OUTER DIAMETER:500 mmINNER DIAMTER:280 mmLENGTH:650 mm
Materials :- GFRP Glass fiber reinforced polymer (60 vol% E-glass) Density (ρ):- 2 gm/cm3
Volume of turbine (v1)= (D02 - Di
2) l = (5002 - 2802) 650 = 87.60106 mm2
Volume of a blade = l h b = 6501105 = 357103 mm3
No. of blades = 6Therefore, total no. of blades(v2) = 357103
= 1.785106 mm3
Therefore, total volume of turbine (v)= v1 + v2
= 5.9106 + 1.785106
= 7.685106 mm3
Design of Shaft
Diameter of shaft:103mmMaterail-C-40
Design of Shaft Material: C-40 Tangential force (Ft) = 340N/mm2
Shear force(Fs)allowable = 170N/mm2
CALCULATION OF DIAMETER OF SHAFT We know torque applied by turbine blade T = 128700 N m
Torque (T) = Fs induced ds3
128700 = fs induced 203
Fs induced = 81.9 N/mm2
As induced stress is less than allowable design is safe

RESULT AND CONCLUSION
As per our setup we were able to glow a 3v and 12v LED lamp for the average speed of 135 rpm.
Hence we are able to generate energy from tidal waves which in turn can be stored in battery for future use.
By Above Study we concluded that this is Good alternative Source for current methods for Generation of Electricity.
