Do we need separate two-phase solver? #9

I am growing more and more confident that we do need a separate two phase solver which works with PBEDiameter. Currently we are combining twoPhaseEulerFoam with PBE library to deliver new models, but this has several drawbacks which I will keep listing here:

redundant solution of phase continuity equation,
inconsistent properties, especially surface tension (surface tension is used in interfacial calculations, but in breakup/coalescence models).

Perhaps this is not necessary. The redundancy can be removed by not solving one fewer equation in PBE.
