Simution of Bubble Column Reactors
Posted Sun May 18, 2003 @10:01PM
Print version Email story Tweet story
Help Desk I am Ph.D student and doing bubble column simulations...problem consists of sparging air in a column filled with water. I am using FLUENT 6.0 and FLUENT 4.5.6 for the simution. I need a help in specifying the boundary condition at the top to model the escaping air.

As such I am putting a velocity inlet as the top boundary condition, but resulting in convergence problem. I tried outflow or outlet condition, which is little bit unrealistic as air is escaping from the top surface...Can anybody help?
