Hi
I wish to model a tube flow with porous walls.
There is a fluid flowing inside the tube and a fluid flowing outside the tube.
I want to model this fluid-fluid interaction that happens through the pores.
How do i do it ?
Hope someone can help me out.

Did you try using the porous zone option in cell zone conditions?

Thanks for your reply!
What boundary conditions should i give while meshing it in gambit ? porous jump doesnt seem to work as it shows an error while opening in fluent. I think i have not quite understood the jump boundary condition properly.
And regarding your suggestion, my model consists only of porous walls. Will porous zone work for this too ?

I am not too familiar with Gambit. Also, as far as I know there isn't a porous wall BC. You can create a different part (or body) while meshing it and define the porosity in the cell zone condition.
