Hi everybody, I have just registered! My problem is that I am trying to simulate a degassing boundary condition for a three phases bubble column reactor in FLUENT. As you may know, there is a degassing BC available in Fluent, but it can only be used with two phases Eulerian model, so I am trying to solve this issue by writing my own UDF.

Currently my aim is to place a mass sink in the cells near to the outlet in order to eliminate all gas. However, I have read that it is necessary to define a momentum source where a mass source is defined.

So what I would like to know if somebody has tried to model this kind of problem. If not, I would also want to know how does the degassing boundary condition work in Fluent so I can extend the code to a 3 phases model.

Thank you very much.
