S-A Turbulence Model and drag prediction
Just needed everyone's opinion on the use of the S-A turbulence model for drag prediction of airfoils.
I have used the S-A model for predicting Lift Coef.. at different angles of attack and the results are very close to the wind tunnel results, however I havent had luck with the Drag Coef.. values?
Which turbulence model would predict Drag as nicely as the S-A does lift?
Many thanks in advance.
