Impliment the Drift flux model or mixture model

rapierrz · June 23, 2015, 04:03

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.

Hi

Did you find a solution to your problem? I am working on the same sort of problem, any help will be appreciated.

Regards
