Default interFoam (and other multiphase solvers): What is solved?

Does interFoam solve 2 continuity equations and 2 momentum equations?

If so, are these continuity and momentum equations solved for (1) the phase specified by alpha1 and for (2) the mixture of both phases?

Also, for n phases, does multiphaseInterFoam solve n continuity equations and n momentum equations?

(I assume that I will eventually be able to figure this out by myself from the source code when I have a better understanding of C++, but for now, I need help... )

Thanks!
Mike

No. Both formulations (two phase and n-phase) solve a single set of momentum equations NOT one per phase. A true multiphase formulation would be useful, but as yet there isn't one that combines with VOF interface modeling in OF. (AFAIK anyway...)

Hi mconroy,

there are some really good hints about how interFoam and twoPhaseEulerFoam is implemented in
