k-omega SST with interFoam.

paka · October 15, 2010, 00:24

Can anyone confirm if k-omega SST model works with interFoam or so far only k-epsilon model is applicable?

Someone mentioned interFoam solver is only valid for k-epsilon model.

Thanks,
K

It should work fine with any solver that uses the run time selectable incompressible turbulence models.

so any solver that has the following include line should have access to all turbulence models?

#include "turbulenceModel.H"

The two fluid models seem to still be restricted to the Gosman k-epsilon model.

Not quite, there are separate compressible and incompressible models and some solvers like bubbleFoam have hard-coded turbulence models.

interFoam is fine though.

Yes of course. Are the multiphase solvers under applications/solver/multiphase/ generally restricted to incompressible turbulence models? I noticed there is a compressible version of interFoam as well.

Yes, most of them use incompressible turbulence models. Even compressibleInterFoam uses incompressible turbulence modelling. I can't say I have looked at all of them in detail though.

Right, thanks!
