K-Epsilon Realizable
 

The k-Epsilon standard is not good for the anisotropic turbulence cases. The Realizzable version? Is it good? And why?

thanks

std k-e model is non-realizable model that means the eigen values of the reynolds stress tensor is negative. This is not true in actual flow. To overcome this limitation, realizable model is proposed. so it should give good results.
