Bad results when compared with Wind Tunnel

October 23, 2006, 01:05

I am having very bad results in airfoils drag and lift forces for any kind of airfoil but specielly with hight attack angle and flaps deflection. I´m comparing this results with obtained in wind tunnels and I´m very disappointed.

I tried many turbulences models without results and meshes.

I´m using CFX and fluent.

Any sugestions?

Thanks.
