Hi guys:

I have a question on two phase flow modelling. The issue is how do you calculate the velocity and momentum for a phase in a homogeneous flow simulation (mass weighted or volume weighted)?

Since it is homogeneous--- both phases have the same velocity. If you want to extract the superficial properties... afaik they are calculated from the "alpha"- so they are "volume weighted". Correct me if i am wrong!!
