About the porous medium heat transfer

Dear all:

Now, I try to using the FloEFD to simulate the heat trasnfer of porous medium.
I have a question for the thermal conductivity of porous medium.
I must input the thermal conductivity of solid or the effective thermal conductivity of solid.
If anybody know, please tell me.
Thanks.

Hi Icweng,
the thermal conductivity is the one from the solid material. That doesn't change because it is a porous medium as it is a material specific parameter. What changes is the density which is why it is refered as "density of the porous matrix".

Regards,
Boris
