Hi to all,

I am working on a multiphase model in OpenFoam with two regions i.e., one porous media and the other is fluid.

I am wondering which boundary condition I need to apply for the interface, so I would be able to define contact angle for the permeable wall (interface) and also let the species go through it (permeable wall)?


Please, see the brief schematic below

Thanks,
Abouzar

region 1: gas mixture+ liquid water droplets

------------------------------ permeable wall, I need contact angle here!

region 2: porous media, with porosity, K
