Which Multiphase Model?

Bob

Hi,

I am having trouble in deciding which multiphase model is best suited to solving my problem.

Basically I am a modelling a straight sided cyclone (vortex tube) that is placed in a large pressure vessel so a lquid level comes half way up the cyclone. Under operation the swirling gas will impart momentum onto the liquid phase and start it rotating so a "v shaped" profile shall be formed inside the cyclone. The gas should exit out the top of the device.

I have tried using the VOF implicit option under steady state and transient but I cannot get the liquid to take the correct profile. Am I using the correct model? What are your suggestions?

Many Thanks
