Re: choice of turbulence model
In a recent training class, I made a comment on the similar question. The answer is: (1). run 3 cases with different turbulence models ( I hope that you are using a commercial code), (2). take the average value from the three results. ( curve fit through these three sets of result would be more scientific) The choice-1 is more economic to run, the choice-2 requires finer mesh, the choice-3 is not widely used ( harder to get some feed back). The above answer is not a joke.
