Dear Colleagues,
I am working simulating a vertical oil-gas separator in ANSYS CFX.
The inlet conditions are:

Liquid mass flow (lb/s): 10,04071181
Gas mass flow (lb/s): 15,50694444
Liquid Volume fraction : 0,041947644
Gas Volume Fraction: 0,958052356

As you can see, the liquid Volume fraction is very small.
My doubt is, Which of the two multiphase model is better for my case, Euler-Euler or Euler-lagrange?.

I have read a lot and I am almost sure that I can use the Euler- Euler since it is the most general model, wheras lagrange-euler is often used to tracking and for solid- gas phase.

What do you think???
