Default K omega
Posts: n/a
I have done steady simulation on airfoil at low reynolds number (800000) with K-omega SST transitional and yplus less than 1.0 and the result is little far from experimental (even the angle of attack is less than stall angle), I'd like to know if in fluent the roughness is set to zero by defoult for k omega sst or not, and if not how I I can eliminate it..

thank you
