Hi All,

I am currently attempting to model stratified flow in horizontal pipeline (water/steam) and is new to openFOAM. I would like to implement non-uniform boundary conditions for each phase but is finding it difficult to do so. The main boundary conditions which I am interested in is the phase velocities and void fraction. The solvers which I have been playing with have been interFoam and twoPhaseEuler.

The main questions which I have is:

Is the solvers which I am attempting to use capable of handling separate boundary conditions per phase? and of so how can I do it?

Any help will be greatly appreciated

interFoam is NOT written on a per-phase basis so only a single BC is used for phase boundaries. You could have a non-uniform BC condition patched in using something like groovyBC. twoPhaseEulerFoam is written per-phase and may be appropriate for your case depending on conditions--I am less familiar with this route.
