Lift & Drag
 

I am analysis the aerodynamics of a formula sae car as a final year mechanical engineering project. I have run some 2d simulation. The results seem to make sense except for the lift and drag coefficient which are totally unrealistic. I have tried to find out what is wrong with no success. If anyone might know where i might have gone wrong, I would appreciate if you get back to me.

Thanks

Change your reference values apropriatelly

A 2D Formula SAE CAR? I would like to see how that looks like!!!!

Re: Lift & Drag
 

I have and it is not making any difference. I cant think of anything else that might be wrong. Could it be the mesh?

Yes if your mesh is coarse that you get very strange results for the drag and specially lift so try to refine mesh and try again Have a fun Rashad
