Hi friends,

I want to implement drift flux model or mixture model in openfoam but I have problem with relative velocity.

Anyone know a formulation for relative velocity that is function of volume
fraction in flow in a 2D channel???

for example Vpq=Vrc (1-alpha)^a

a and Vrc is constant and Vpq are relative velocity.

thank u.
