Before 2 years we made a CFD model of the conjugate heat transfer in ceramic regenerative heat exchangers aiming a heat recovery in air conditioning systems is elaborated. The transient thermal and fluid flow fields in such a regenerator are obtained via numerical solutions by the finite volume method. The models are validated by comparing the computed and measured outlet temperatures and the heat transfer coefficients obtained by the simulations and the theory of similarity.

Now we are doing more deep research, but at this time we can't apply the model of the above article. So we have to create a new CFD model Conjugate Heat Transfer in Porous Media, but we wondering how Fluent simulate the porous. We've got a honeycomb matrix with square channels and we would like to imitate as porous media. If we change the honeycomb structure and for example, we use rectangle channels how does influence the porous media, what do we have to change? How does Fluent know what is the structures of porous media or we must write a UDF for this problem. Thank you!
