Interface smearing Euler-Euler

[j.j.a.v.zutphen]

I am doing a 3D steady state inhomogeneous Eulerian simulation of a gas-liquid separator.
My focus is in looking how much gas leaves out the liquid outlet in the form of little bubbles.
I have to define the bubble diameter myself but this greatly influences the outcome.
Also the liquid-gas interface starts smearing which is unrealistic. I am using a multi-fluid VOF hybrid model with the interface defined sharp/dispersed.

How does the simulaiton define where a disperse phase is present/created and how do I prevent it from smearing by having droplets everywhere.

Hopefully you understand what I mean by this, I will gladly explain more.
Kind regards,
Jasper
