paper on k-eps/k-omega

Hi!

Does anyone know a good paper on the differences of the k-eps and k-omega models. Why are they so different? I mean omega=eps/k.

Have a look at the paper by Wilcox:

Wilcox, D.C. - ``Reassesment of the Scale-Determining Equation for Advanced Turbulence Models'', AIAA Journal, Volume 26 number 11, 1988, pp.1299-1310

and the one by Menter on the SST model:

Menter, F.R. - ``Two-Equation Eddy-Viscosity Turbulence Models for Engineering Applications'', AIAA Journal, Volume 32 number 8, 1994, pp.1598-1605

They give a good explanation of the differences between k-e, k-w, BSL k-w and SST models.
