Hello all

I am reading the multiphase flow and trying to simulate 2D two-layer Rayleigh Benard convection in ANSYS Fluent using volume of fraction method. I have read the theory guide but couldn't figure out how the momentum equation and energy equation will get simplified. Any help over this.

Thank You

Simplified against what? The VOF model adds in terms for free surface motion, it doesn't remove anything from the base solver numerics.

I mean I what will be the form of equation, to be more speciifc, how the u and v velocity for each phase be taken care of in momentum equation and how the enrgy of each phase be taken care in energy equation??
