A discussion on turbulence models

Using SimScale Fluid Flow / CFD
1

I wanted to open a topic on turbulence models since I often see questions about it but it’s not yet covered in the SimScale documentation (it’s in progress :wink: ). Here is a list of the models currently supported by SimScale

  • Laminar
  • LES Smagorinsky
  • LES Spalart-Allmaras
  • RANS k-epsilon
  • RANS k-omega
  • RANS k-omega SST

A couple of questions to get this discussion started:

  • What are the best resources for understanding these models and how they should be used?

  • How can we be sure that the turbulence model that has been selected, is in fact within an acceptable range of accuracy? Does anyone have examples?
