Hello

I am totally a newbie to OpenFOAM. I have a question that will affect my research plan. I understand that their exists a multiphase flow utility interFoam and a flow through porous media utility rhoPorousMRFPimpleFoam . I wonder if it is possible, using available utilities, to have a multiphase (free-surface) flow model (water+air) at which a porous zone exists (Forchheimer) in which only water flows. I would appreciate any tips or guidance of any sort that would help me plan a tentative time schedule if I need to dig in the C++ code.

Best regards,
Hisham El Safti

Hello Hisham,

The solver you need is porousInterFoam but unfortunately there is no example yet. This solver is able to model two (incompressible) fluid flow with porous zones.
in the porousZones dictionary, you can change the permeability values and the Forchheimer parameters.

Best Regards,
JTT

Hello JTT,

Thanks a lot for your quick reply. I didn't find the porousInterFoam solver in http://www.openfoam.com/docs/user/st...p#x13-890003.5 and of course no tutorial. I would be glad if you can advise me on how to obtain more information about it and I think a tutorial would be highly appreciated.

Another important question: Is there a similar utility for compressible flow? or else is it easier to work on this solver as a base for an incompressible flow solver or is it better to base the work on compressibleInterFoam & rhoPorousMRFPimpleFoam

I would also be grateful if you can guide me to helpful literature.

Thanks again

I also read this:

and wonder if anyone have coupled compressibleInterFoam & rhoPorousMRFPimpleFoam
???
