Fluent's Mixture model in CFX

FLuentSwitch

Hi.

I'm trying to redo a CFD simulation done in FLUENT using CFX in stead. It has to do with a hydro cyclone with water/air with an air core in the middle. The Fluent approach was using a Mixture Model in the multiphase options instead of the more difficult Euler-Euler approach. How do I set the corresponding settings in CFX. Does it have a "mixture Model" and what it's "name"?

Thanks
