Default Which is the best? Standard,RNG,Realizable
Posts: n/a
Without exp data for comparison, at all the same set-ups(problem, grid, bc, etc), the results are different by using Standard or RNG or Realizable turbulence model. For my computations, heat transfer between three models are slightly different, but the inlet-to-outlet pressure drop is much different between RNG and Realizable. Why? I don't know.

Thank you.
