Udf for heat source

A porous medium is included in a domain. I want to define a heat source to the porous medium which will be a function of the temperature difference between the porous temperature and the domain temperature. Thanks for any help, Thomas

It's possible. The DEFINE_SOURCE macro is available for your problem.

If you're using the standard porous media model in Fluent 5 or 6 you won't be able to model interphase heat transfer or have a model that assumes non-equilibrium between the two phases. Fluent assumes, a single energy equation for solid and fluid as described in the manual.
To model a porous media without thermal equilibirum you need to use udfs/udss... I have presented some code for this in 2000 and 2001. Its also in the udf repository....search the archives for the posts/code. Greg |
