Dissimilar fluids for two separate inlets in compressible flow modeling

Zahid123 · August 30, 2022, 12:38

Dear SU2 experts,
I am currently using the NEMO_NAVIER_STOKES solver to simulate compressible flow. In my model, I have two separate inlets. In one inlet, I have to assign a gas composition (N2:0.77,O2:0.23). The another inlet will have a gas composition (N2:1.0). Currently, I am assuming the inlets as farfield instead of supersonic inlets, as farfield is the only marker option Nemo is accepting in the version 7.3.1.

Would you be kind to advise me the way to assign dissimilar gas compositions for different inlets, to be specific for the compressible nonequilibrium flow modeling (FLUID_MODEL= SU2_NONEQ) in SU2 Nemo! If it is possible, is there any relevant SU2 tutorial I could follow?

Another question, is it possible to assign a permeable boundary in SU2 solver?

Thanks for your time. I appreciate.

Best regards,
Zahid

Hi Zahid,

I am one of the developer of NEMO. Unfortunately, we do not have the capability implemented yet. I have played around with a bit, but haven't had time dedicate the issue.
