Compressible Multispecies Gas Flow

cwl19 · July 12, 2013, 15:03

I am trying to solve for the case of a 3 species gas flow in a chamber with a center partition. I have no idea how to handle multispecies gas flow in OpenFOAM. Any help is greatly appreciated!

Try species transport with something similar to scalarTransportFoam. For turbulent flows, I would look at this thread

Depending on if your species are chemically reacting or not, this may be good enough for you. You might want to look into passive scalar transport, but of course all this depends on your system. good luck.
