Hi Foamers,
I am trying to model a air pump using interFoam, Need to calculate mass flow rate of individual phases at outlet, the system has one inlet with air and the second inlet is water (but air and water can go in and out through second patch), mixture of air and water at outlet is expected. Is there any way we can quantify the water flow rate alone at the outlet.

Flow rate of mixture * volume fraction average at outlet phase yields phase flow rate.

If the air and water velocities are differents, i'm not sure of that answer because of the consideration of the air velocity in the flow rate of mixture. Its my case and that block me in my problem.

I also just tried to do this. Here is the solution I adopted:
