Study of a Rear wing
 
Hi every body!

I'am doing a study of a rear wing for a sportcar and I have some problems.
Indeed, I have somme difficulties to find the right boundaries conditions

I put Velocity-inlet where the fluid is coming and where the fluid gets out I put Pressure outlet but i have "reversed flow" and i don't know how to fix that...

Thank you

Max

Move your outlet further away from the wing, it must be in the re-circulation zone in the wake so it needs to be at least 10x away from the wing, where x=car length.

Also, the wing should be modelled with the vehicle, they dont work in isolation because the angle of attack is too high - they only work in conjunction with the upwash generated by diffusers.

Ok I'll try that! Thank you! ;)
