Hi-

I have to define a porous jump boundary condition and am confused. How do I define the porous jump coefficient? I mean, where do i get that value from? I am using a HEPA filter. I dont know its permeability. Where can i get the permability from? I know the pressure drop across the filter.

Try to reconstruct the permeability from your known data according to fluent user manual Or try to set-up a simplified porous media model to measure by CFD simulation your unknown parameters.

best regards
