Hi all, I am student and for my project have to simulate a wing in three dimensional in prostar. i used ideas to generate the mesh and have taken it over into star-cd but am not sure which Turbulance model to use and what values to use for intensity and length. Can anyone please help?

Thankyou Hussein

for a standard problem use standard k-e

intensity and length depends on your modells size and the flow speed. it can't be answered generally!

i did something similar but in 2d, the best results as far as I remember were given by reynold stress followed by k epsilon

Look for AIAA Drag Prediction Workshops material
