Hi dear Foamers,

As you know the description of twoPhaseEulerFoam says that "Solver for a system of 2 compressible fluid phases with one phase dispersed, e.g. gas bubbles in a liquid including heat-transfer."

How can I use this solver for incompressible fluid?

Thanks a lot

You can set the diameterModel in /constant/phaseProperties to "constant" with "constantCoeffs" and give a diameter for the resp. phases. I think this should give you incompressible phases.

Thanks BlnPhoenix for your reply.

What does diameterModel exactly mean for a continuous phase?

I guess if its magnitude is large enough then it will be continuous phase (like fluidisedBed tutorial).

I think putting equationOfState rhoConst; in constant/thermophysicalProperties.incompressiblePhase would solve the problem. Am I right?

Yes, in areas where the dispersed phase gets larger than the continous phase these two get blended, so e.g. water is now dispersed in air and these water droplets have the prescribed diameter.

Yes, i think your correct.
