im_lenny is on a distinguished road
I am modeling the flow of a high speed gas jet (Mach 0.5) into a large volume of water using OpenFoam. I would like to model the turbulent interface between the phases, so I am using a full 3D simulation with LES. I am primarily concerned with the portion of the jet near the exit, where the gas flow is slowing down and expanding as it transfers momentum with the water.

Should I use a Volume of Fluid method (compressibleMultiphaseInterFoam) or a Euler-Euler method (twoPhaseEulerFoam) for the solver?

The Euler-Euler method solves conservation equations for each phase separately and assumes that one phase is dispersed in the other. (Although there is a mulitphaseEulerFoam, so which phase is dispersed in the other probably doesn't matter.) The concern with the Euler-Euler method is that the gas would artificially disperse into the liquid too quickly.

The VoF method only solves one set of momentum and pressure equations for the system. The concern is that the momentum transfer between phases won't be strong enough and the jet will take a longer distance than it should to slow down.

Again, which solver should I use for a high-speed, high-flow-rate gas jet into water?

Thanks.
