Replies: 12 K-epsilon vs. k-omega turbulence modelling Views: 23,649 Posted By LuckyTran Hi, I am assuming you are working with air. ... Hi, I am assuming you are working with air. The laminar or molecular Prandtl number for air is 0.7. If turbulence enhances heat transport (via turbulent fluctuations) then how can the turbulent...

I agree that if you change some model constants that shouldn't be changed, that it can can an effect on the results. Yes. Yet again there is no surprise that you can change the turbulent Prandtl...

I understand why everyone would like to compare Nu and f for two models, because it feels like a low hanging fruit. For separated flows, k-epsilon and k-w SST models can and generally do give...

The SST k-omega model reduces to a standard k-epsilon model away from walls. Near walls, the SST k-omega uses the the omega formulation whereas the realizable k-epsilon uses the epsilon...
