compressible scalar transport euqation
Hi all,
I added three scalar transport equations to my compressible solver like this: Quote:
As long as my temperatures don't differ very much in my flow, I am getting proper results. But when I get regions with higher or lower temperatures, then the sum of my species exceeds 1 in the hot regions, where rho is small. In the colder regions, where rho is high, the sum of my species is too small. So there might be a problem with the coupling of the transport equations with the energy equation. I know that in other Solvers like rhoReactingFoam there is applied a multivariant scheme (mvConvection) to couple the energy equation with the species transport. But I thought if my species are all the same this is unnecessary. Can anyone help me to solve my problem or has anyone any experience with similar problems? Thanks in advance! Best regards Chrisi

Hi,
perhabs someone will once have a similar problem. Here is the solution for my problem: I changed the interpolation schemes and than everything was all right: Quote:
