Prdctn of lift/drag co-efficnt of 2D foil influent
 
Hi, I'm working on prediction of lift and drag co-efficients using Gambit/Fluent and need to compare the results with experimental data(from Sandia laboratiories) for 2D NACA0018 airfoil. Ive been able to predict the pre-stall scenarios quite well in almost all turbulant models(SA/K-eps/K-omega).But the predictions of co-efficients in post-stall scenario is far from comparison. Please give me some suggestions/tips to improve my post-stall prediction using Fluent.
