Boundary condition for a porous wall

deepbandivadekar · January 15, 2018, 05:32

Good morning!

I want to use "buoyantBousinessqSimpleFoam" for a problem involving porous medium. There is a porous wall as one of the domain boundaries over which there is flow. However, I want to define this porous wall as an inlet as well (since it is porous assuming I can find the outlet conditions of flow through the porous medium, which then can be kept outside of the domain). So that would mean there will be two inlets one the usual and the other through the porous wall.

What is the best boundary condition for such a porous surface? Is there any way I can use a "wall" as well as a "velocity inlet" boundary condition to it? How?

Thanks

Hello Deep,

I hope you are doing fine.

I am also searching for a similar kind of boundary condition. Can you help me out with this if you have already resolved this problem?

Thanks and regards
