water-oil cyclone separator
 

Hi

I'm a new user of fluent and I try to modelling a water oil cyclone separator. I use RSM model with Mixture (because oil volume fraction equal 0.4 or more). I select PRESTO! and PISO (I also tested with Standard and PISO). My boundaries are outflow because i don't know the pressure outlet. After modelling, I obtain very strange results. Water leaves by overflow (and underflow) and oil just by underflow. Somebody can help me? Thanks, nicolas.

Outflow boundaries can it be the cause of my problem? I think that is true. So since i don't know pressures at outlet, how can i solve the problem? Please help me. I am very blocked. Thanks.
