Modeling heat transfer through a porous media
I am a beginner, I am trying to model heat transfer through a porous medium.
I am modeling a cuboid in the design modeller, meshing it there and importing it into fluent.I am then modeling the fluid cell as a porous zone with given porosity and imposing the boundary conditions which include uniform heat flux on one surface and all the other surfaces adiabatic and velocity inlet boundary condition as well.
The heat flux does not seem to have any effect on the porous media, I am getting unform temperature contours through out the model.
Can some one tell me if I am doing the modeling right.
Couple of related questions/comments:
1. What values of porosity are you using?
2. I have tried using porous media with a wall temperature too. Compared to such a case, my (limited) experience showed that using a heat source/sink workes better in porous media.
I had a somewhat similar problem in FLUENT, and could not get any satisfactory reply. Please refer to the following threads:
PS: It would be better for you to post in the FLUENT forum than the present one.
