Default k-epsilon turbulence modelling

Am fairly new to CFD, was wondering if anyone could clarify the differences between the standard, realisable and RNG k-epsilon models in fluent, have been able to find some info on the RNG but very little on realisable.

Thanks for help

First thing you may want to do is that you refer to fluent documentation. I have found some useful info on each turbulence model. Though such info may not be detailed, it is a starting point. In general, K-e models share a common concept and hence whatever material or text book you find on a standard k-e modeling will help.

Cheers Amr

The Fluent documentation is a good start. It mentions situations where each model has its benefits.

In addition, a book on numerical solutions (with a section on CFD, of course) should provide help.

Finally, many journal articles have been published discussing turbulent solution schemes and their application to a specific part, e.g. a nozzle.
