      Can anyone help me in setting up the model for a multi-phase simulation? I am trying to simulate the flow of two phase hydrogen through a centrifugal pump. I am prescribing different vapour volume fractions at the inlet of the pump (from 10% to 50%) to see how the pump reacts to the presence of the vapour phase. I defined two different fluids with constant properties. I want to use the thermal phase change model.

      Which settings are the most appropriate for multiphase, heat transfer, interphase transfer and so on? 

      Thank you very much for your help

      You need to provide resistances on each side of the interface. The modeling guide does provide some hints there. That is most important settings along with the assumption of a particle size.
