Have you already find out how to do the calculation?
If so, I'm also interested.
Thanks in advance!
As far as I know, there is no multiphase calculation available in a Flow Simulation study. You can only study discrete domains of liquids or gasses.
I know it's possible but I've never done it before. I'm copying what SW has said about it. hopefully it helps you:
Yes, it is possible to use the “Tracer Study” to measure the “Tracer Mass flux” to show where condensation/vaporization occurs along a surface. It is possible to check “Liquid surface” option in case of using water (H2O) as tracer. In such case “Tracer Mass flux” parameter will show us places of condensation and vaporization.
The following limitations are applied to the tracer condensation model: Can not calculate how much tracer falls at a particular surface for entire period of time. There is mass flow rate calculated on surface, but not the resulting mass. Consequently, cannot simulate the real film thickness and all effects caused by this film such as additional thermal resistance.
