Is there any test case to test turbulence modelling for two phase flow?

Hello All

I am looking for a test case for to verify turbulence model in a two phase flow system. I have spent hours for the same. Can anyone suggest one ?

Are you talking about a test case that uses bubble induced turbulence model that is programmed into an Euler-Euler solver? I'm not aware of any..

There is the kOmegaSSTSato for example that you can try to use for experimental data that maybe can be found online..

Hello

Thanks for the reply.

My aim is to solve atomization problems in two phase flow. Since turbulence instability of the liquid jet plays a major role in the breakup. I am looking for some standard test case for analyzing turbulence instability of my solver.

One way is to validate it with experimental data available for jet break up. But since it is going to be a validation for the solver so I am looking for a standard numerical test case for analyzing turbulence instability in two phase system.

And yes the solver is Euler-Euler solver similar to s-CLSVOFFoam.
