Fluent setup for Renolds No of 0.15 to 0.7 milion
 

hello every body : I have confused what model to use for low reynolds numbe r flow around the german low speed airfoil FX . I used K-omega and K epsilon modles but the drag was about 50 % dieffrent from EXPerimental (dated both at 1930 and 2004). results

I want the fluent set up model for low Re. number as 150,000 to 500,000. I mean is laminer flow ok? or Some turbulance modle is better?

thanks M. Essuri

Hi, You can try with the Spalart Allmaras model. It was developed to work with aerospace applications.

Good luck!
