Reply To: Trouble with population balance for bubble column simulation

Thank you for the answer! I was away traveling, so please excuse my late reply. 

Before I try to make a more refined mesh, I wonder if you think a polyhedral or a poly-hexcore created using fluent meshing should be sufficient for the simulation, or if I should try to improve the hex mesh I created using ICEM? 

 

I think the bulk flow is behaving as expected. The water is flowing upwards above the spargers and is flowing downward/recirculated between the spargers.
