gas diffusion through porous solid media

flo777 · May 14, 2015, 13:16

Hi,

I am trying to model gas diffusion through a solid media with mass/heat generation.
I have the conservation equation for the gas (with generation term), and the heat diffusion through the solid (with heat generation term).

Please suggest what are the appropriate ways to approach this.
From my understanding, Fluent treats the porous media as fluid? Is there another way to couple the equations?

I should mention that my problem is axisymmetric.

Thank you,
Florin

I am working on the same thing. I have a reaction that causes gas species to offgas from the solid phase in my porous zone. The solution diverges when my UDF defines that species source to be dependent on T and partial pressure of the species in each cell.
