How to model two-phase flow using Euler- Euler approach between hot vapor and water to track the interface between liquid and gas in FLUENT?

I want to model two phase flow of hot compressible gas (H2 at 2000K) and water ( 300K) using Euler- Euler approach. The geometry is similar to that of a Tee Junction. Hot gas stream from one inlet...

Why are the velocities so high in my Boussinesq approximation Fluent simulation?

Hello, I have a mechanism where air rises due to convective flows. In this simulation, nothing is driving the air except this. I understand that the Boussinesq approximation only works for small...
