Multiphase Mixture Model fluent5.4
 

Hello,

I try to model a secondary clarifier with the ASM mixture model (Fluent5.4) especially the settling of the activated sludge due to gravity and the occuring hindred settling effects. But at the moment I have got difficulties to reproduce the results of my onephase model. Even without slip the flow patterns are totally different. Does anyone have experiences with this model or with a multiphase model for settling due to gravity?
