Compare different Turbulent models
I tried to find out the same geometry but different turbulent model (standard k-epsilon, RNG k-epsilon with low Reynolds number models), how can I compare the results got? Is there any standard procedure to follow?

Re: Compare different Turbulent models
Compare them on a case with experimental data that is close to yours. Here's an example of how to do it:

Re: Compare different Turbulent models
We've done a detailed comparison of EV turbulnece models for few benchmark flows. You can see the following references for the detailed methodology
