Default Stall-Angle of an elliptical cross-section body
Posts: n/a
Hi there,

I hope anyone can help me, because I'm really desperate.

I need to calculate the lift coefficients versus angel of attack of different bodies with elliptic cross-section.

As a 2D-simulation failed, I am now working 3D, and doing the simulation with the LES-solver. I have a very fine Grid, and my y+ is about 1.

Nevertheless the lift coefficient does not drop at the critical point of about 20, but has a further increase.

I am very grateful for any kind of help.
