Rankings of RANS based Turbulence Models
hello all,

I wonder if by now there exists any "look-up" table for choosing appropriate turbulence model (two equation, one equation or zero equation) for computing RANS (2D/3D). Some of criteria could be:

1. Accuracy in prediciting seperation/ reattachment/ re-laminarization

2. Accuracy in predicting heat transfer

3. Accounting for anisotropy of reynolds stresses

4. Accounting for compressibility of fluid

5. Ease of programming

6. computing cost/time

How about combination of one or more of the above criteria ???

Maybe the CFD experts using this forum based on their experience/knowledge start developing ranking tables!!
