simulated 3phases flow in pipe

Hello everybody
I want simulate 3phase flow in pipe.
How can define amount of concentration ?( for example 500 ppm)

Multiphase models use volume fraction to track the amount of each phase. So you are going to have to convert the concentration to a voluem fraction.

But if you are talking ppm does this imply the stuff is dissolved, not mixed at a microscopic scale? If so, then a multi component or additional variable approach might be more appropriate, rather than multiphase.
