hello everyone

I want to use turbulent models but dnt know which to use n also I don't the differences among the models.

so can u plz explain
what is RANS approach?
what is SAS approach?
DES approach?
LES approach?

I want to know actually what is basic differences among above model?
Is grid generation (meshing ) affects the selection of model of turbulence?

please reply as early as possible....

thanks in advaanve

You should just read any good book about CFD. These questions are much too extensive for a forum. I doubt anyone will help you satisfactorily with that.

I agree ... just as suggestion, start from a reading of the Peric & Ferziger book then the Pope book. But you need time to go in ..
