filtration
 
Hi
i have a question
How can i simulation filtration process in fluent for two phase?
i am run my simulation in fluent but do not separate secondary phase from primary phase

It depends on what your goal is exactly. Filtration can be simulated using porous media conditions so you don't have to model the individual openings of your filter medium. Are you sure you want two-phase flow, is it any important to represent it that way?

thank you
my filter created of several layers
boundary condition for filter is wall
but when i run the program
no phases separation
i am uses mixed approach and eulerapproach

Okay your information is vague.

1) How have you defined the porous region?
2) Why do you need the two phases? Can a single phase represent a filtration process?
3) What are you exactly trying to achieve here?

thank you
1- i am define porous region =(region is lace -mist eliminator)
2-at system air carry over water droplets toward filter(lace-mist eliminator_
thus i am define two phases
air=primary phase & water liquid =secondary phase
3-two phase flow toward filter and secondary phase strike to filter and loss momentum thus tow phase separation
