Dear friends
problem: Fluid is flowing through a multilayer porous pipe. I know the boundary conditions for inlet which is pressure and outlet which is mass flow rate in the fluid domain my question is: How to define inlet and out let in the porous domain. I assume in the porous domain as inlet: Cartesian velocity components equal to 0 outlet : pressure equal to 0 Is my boundary condition correct? Thank you Regards Shashwat |

If that matches the experiment you are trying to model then probably, yes.
But it does seem weird to have a mass flow outlet on the main flow, but zero pressure at the porous outlet. Why is it different? If the flow is not significant in the porous material just put a wall there. |
