Turbulence Modelling

Apurva

Hi,

I am at present working on implementation of high reynold's number K-epsilion turbulence model and k-omega turbulence model.

While refering to the book by Versteeg and Malalsekra, I have the wall functions for y+ between 30 and 500, but what should be the wall function for low values of y+ say around 1.

In case of k-omega, what should be the value of omega.

Also how should be the boundary conditions be implemented in case of both.

Thanks and Regards
