Default Cell reynolds number and turbulence
Gavrilo Bozovic
Posts: n/a

I think I'm missing something about the "cell reynolds number".. Is this simply an indication of the calculation stability, or can it be used to infer the flow regime?

My problem is the following: I'm running a CFD simulation in which I really don't know whether I'll get a laminar or turbulent regime. Now would it be possible to solve the problem using Navier-Stokes, then consider the Cell reynolds number, and then pass to k-epsilon in the case a turbulent flow is detected?

Thanks in advance for any help!
