How to Create and mesh a pipe with a porous tube insert
 

Hi all,

I need to simulate two-phase flow inside a pipe with a porous tube insert. I investigated a lot though, but still I am confused how to create and mesh such a geometry in OpenFOAM. I attached the schematic of the geometry I am talking about. The inside of the tube insert is hollow and it has a porous wall with the porous front side and empty at the outlet. The outlet of the porous tube insert and main pipe are at the same location. Anyone has a suggestion how can I handle that? I would really appreciate any feedback on this problem.

Thank you,
