SU2 - Porous media / porous jump model

jw-89 · January 6, 2022, 09:55

Dear SU2 users,

in my present CFD project I want to simulate flow through a porous media with known pressure-drop characteristics. In Fluent there is a notion of porous jump boundary condition which is very helpful. Does SU2 have such a type of BC or something similar? If not, maybe some of you have already tried to implement it in SU2?

I appreciate your help/suggestions/hints.

Hi!

We currently do not have porous jump boundary conditions. If you have a lot of time reserved for your CFD project, then this would certainly be a valuable addition! You can have a look at the implementation of the multi-zone approach and extend the interface boundary condition. The starting point will then be this:

https://su2code.github.io/docs_v7/Multizone/

and setting up a testcase with 2 fluid zones connected
The next step is then to understand how interfaces work in SU2, which is done in the file CMultiZoneDriver.cpp
