There is a room with an inlet and an outlet and a porous surface(the green surface in the fig.) which air flows from the inlet surface(which is a part of the room's ceil) through the porous surface and exits from the outlet.
how I can model the porous surface(the green one) and what parameters I need and how calculate them?
