Bubble Foam momentum equation

I guess that if you'd use VSMALL, you'd end up with a huge number if alpha1 is indeed zero. To avoid problems the authors chose a small, but not too small value.

But what if the alpha values that I am working with are also small? smaller than 0.001? then this hard-coded value will affect my results?

should I decrease this scalar value only few order of magnitudes then?

I want to use bubblefoam solver but it prevents on my work, because of bubblefoam limitations.

BubbleFoam limitations

The diameter of the particles constituting the dispersed phase is assumed to be consistent. Aggregation, breakage and coalescence phenomena are not accounted for.

What is your suggestion?
DO you know any solver uses Euler mixture model ?

thank you
