Hello, I'm in trouble about which multiphase flow model should I choose.
The condition of my case are listed as below:

1.gas-liquid two phase flow in a classical venturi tube
2.very high gas volume fraction(98%)
3.I want to observe the phase interface at venturi throat
4.high pressure(60bar)

As usually, the DPM model is recommended for high volume fraction condition, the liquid droplet could be treated as discrete phase. But I also want to observe the phase interface, if I choose VOF model, the mesh volume should be smaller than that of liquid droplet as far as I know. So I am confused about the situation I wanted to simulate.

Thanks for help!
