Maria Teresa Milesi Guest Posts: n/a	Hi, I am studyng some NACA wings with Fluent 5.3, I've chosen k-e realizable models and the non equilibrium wall functions, I've found good results for Cl but I've some problems with Cd (the sperimental value is about 0.0055 and mine is 0.011). I tried also the RNG models with the differential viscosity models, I've found Cd=0.006 (a good value) but the distribution of velocity vectors is very strange (there is a distact in the end). Can you tell me which is the best turbulent models to use?
