Define different turbulence model for each phase (multiphaseEulerFoam)

remidemol · November 7, 2016, 16:30

Hi everyone,

I am using multiphaseEulerFoam for a air/water system and I wanted to know how the turbulence model are defined in turbulenceProperties file ? Is the turbulence model defined for both phases or only one ?
Is it possible to define 2 types of turbulence model, one for water (e.g. K-epsilon) and one for air (e.g. laminar) ?

Thank you for your help !

Does anyone have an idea ?
Thank you

Actually you can't. This is a characteristic of the flow, not the phase. The whole flow regime should be either laminar or turbulent.
