Which Turbulence Model??? suggestions please..
 

Hi all,
I have two (similar) problems.:confused:

Prob 1: I have a boundary layer flow inside a duct with wall blowing.
Prob 2: I have cross-flow (two different gas-species mixing together in normal directions, one at high velocity (10-20 meter/s) and the other at low velocity(1-2 millimeter/s))

What are the turbulence models that might give better predictions for these..?? Has anyone ever seen/encountered some literature reg this..??Kindly suggest me..Help in this regard is highly appreciated..:)

Thanks a lot in advance,
Palani.:)
