Hi everyone,

I have a flow channel in which the bottom wall is in contact with a porous media. Air (phase-1) enters through the channel inlet, flows through the porous media reaching its bottom surface where O2 it consumed and liquid H2O is produced. Then based on the liquid water produced, I calculate the velocity of water that enters the channel through the nearest pore available. Please check the image attached for details (blue=inlet, red= outlet).

In the interface between the channel and the porous media I would like to set a phase-dependent boundary condition type as:

for phase-1 ---> interior boundary condition
for phase-2 ---> wall boundary condition

So that phase-1 can and phase-2 cannot penetrate into the porous media.

Does anyone knows how to do this?

Thanks.
