Report title: Simulation of inviscid flow past 2D airfoil Student: put your name here

General Remarks

Using screen snapshots is unacceptable!I will mark accordingly. Make nice graphs and plots. Export your data, and use plotting software to plot them (Excel, Matlab, or whatever you like). Clear legends and labels are a must. Use proper technical terms.

Make the report engaging and interesting (the rule is: tell me something I dont know)

Text must be concise and to the point (If you feel a sentence is just blab bla bla, remove it. Better a short clear report, then a long, pointless one.).

1 Description of the problemWhat physical problem are you simulating? What are the main physical parameters?2 Numerical Method

Describe which solver options you are using (first-order?Steady?Other?) and typical numerical parameters (e.g. time step size, grid size, etc.)

The most important parameter in every steady simulation is the ratio of the grid mesh size to the characteristic size of the object. If this parameter is sufficiently small (how small? only a convergence study can tell you this), then the simulation can be said well-resolved.

For unsteady simulations, you want the time-step to be small in comparison to the typical time scale of variation of the flow.

3 Results

3.1 Pressure distribution & streamlines

We want to examine changes in the flow field for different angles of attack (pick a few angles from 0 to 20 degrees).

For each angle:

Plot the pressure distribution around the airfoil using iso-contours of pressure.

Plot the pressure at the airfoils surface.

Plot flow streamlines.

Comment on the position of the front stagnation point (point of maximum pressure and diverging streamlines) for the angles of attack you selected.3.2 Lift force

Plot the lift force as a function of the angle of attack.4 Summary & Discussion

Summarize the main results. Be concise and to the point.

Discuss outstanding issues, such as problems you have found in the simulation, and how you would plan to tackle these issues if you had more time.
