Hi all,

I'm simulating a fluid-solid heat transfer system with chtMultiRegionSimpleFOAM.

I would like to make the solid part porous with an openness of 4%, which means 4% of void volume where the fluid can flow.

The problem is that I only see laws like the DarcyForchheimer law available, whereas I only want to use the openness parameter.

Has anyone already come it?

Thanks

Gennaro

Hi Zahraa,

Porosity can be implemented in my case (still liquid) by weigh-averaging the thermal conductivities of the two materials accordingly.

Kind regards
