need some suggestion urgently
 

hi i am doing analysis of intake of high speed turbine and mesh is mapped and using segragated solver. i used one equation model kw model but my simulatio diverges as speed increases from 100 m./s what should i do i also decrese under relaxation factor . can any body tell me some suggestion nabeel

If your flow is compressible have a brief look at Fluent's suggestions for the solution setup. They helped me get my simulation converged.

Hi

It seems that the flow is compressible, since the speed is quiet high. So, segregated solver won't do.
