Mass Transfer Boundary Problem CFX

bfmoura · April 11, 2014, 14:31

I am simulating a problem that I need to put a boundary of zero concentration at the wall and a mass flux defined near the wall or mass transfer coefficient. Is that a way to implement those boundaries? Any information in addition I can provide.

You can set zero concentration at the wall, this is one of the basic boundary condition models available.

You can use a volume source term to generate a defined mass flow rate of stuff anywhere.
