I am trying to simulate multiphase in fluent: water as primary phase and air as a secondary phase in centrifugal pump:


My question is in phase interaction force:-

I choose the following:
Note: I am new to cfd field and my choices depend on very small reading


Drag Coefficient: tomiyama

Modification:brucato

Lift coefficient:hessenKemper-et-al

Turbulence Dispersion:simonin

Turbulence Interaction:simonin-et-al

Global Option: surface Tension Force Modeling
Model:Continuum Surface Stress

Surface Tension Coefficient:constant 0.073

interfacial area : ia particle


In Population Balance Model:-
Discrete
Parameter Kv 0.5235988
air min diameter 0.01 and max diameter 0.0125


Please, any comment or any recommendation on my choices or any advice for changing and choosing other options.
