In fluent, how can I know that which type of K-epsilon model should I use for my problem? For example; Standard K-epsilon model and Realizable K-epsilon model, which one should I use? I saw some different equations of these two models of K-epsilon model,  I know that the difference between Realizable and Standard model is the viscosity coefficient and the dissipation equation. But I want to know the exact purpose to use each one model. Because in my problem, I have to apply source term, sink, mass flow inlet and mass flow outlet in one domain and also I have pressure Outlet, so when I use the Standard K-epsilon model, the solution is not converged, but when I use Realizable K-epsilon model, the solution is converged.
