some questions about SA turbulence model?

June 6, 2006, 05:20

Dear friends,

Now I'm working on numerical simulation for airfoil stall using DES of SA turbulence model(by finite volume method,LU-SGS scheme,dual-time stepping method).But I haven't done any related work in that field.So I have some questions/ problems about it:1)how to define the initial/bounary conditions;2)the model equation should been solved coupled with NS equations or not;3)which parameters influence its computation efficiency and accuracy. Thank you for response!

Hi, Have anybody done any work about that?I think 'yes'.So I wish you can give me some advice or any other help. Thanks very much!
