two phase modelling in bubble column
 

hi, id like to simulate the following setup in 2-d: a rectangular bubble column with stationary fluid(water) inside.oxygen is sparged in thru the bottom with a known flow rate.i have to track the bubble path and get other flow info. what are the boundary conds etc i should use,and how can i model it. thanks in advance

help me to create the geometry of bubble column in two phase
 

How do I create the geometry of bubble column reactor for two phase in Ansys 16?
