Porous boudary condition

forgottenman · November 13, 2011, 15:35

I want to set boundary condition for a porous zone. This porous zone is placed in a fluid zone. I want to find out which boundary condition is appropriate to apply on the interface betwwen fluid and porous zone.
Thanks to All.

Your problem is not clear
please specify it clearly.

I'm simulating a flow of air in a duct. A part of this duct is filled by porous media, so there is a boundary which air needs to interpenetrate and pass over the porous zone. I want to know which type of boundary condition is appropriate for this boundary (interface betwwen pure fluid and porous zone).
Thankyou again.

If you want to simulate the porous zone there is no need to define any boundary condition there. just make a different zone for it.

fluid zone :: porous zone :: fluid zone

define inertial and viscous resistances in that zone in the porous zone .
You are done

It's done
Thankyou so much
