rhoReactingFoam
 
Hello All,

anybody used rhoReactingFoam and willing to put an example case / tutorial on wiki?
If I manage it over this weekend, I will upload...

Can anybody help with this problem?
I am trying to use OF-1.6 from website. Do I need to recompile?

Hi Rachel,

I guess that the BC are not correct. Recheck it.

Hi,

I have a question concerning not only rhoReactingFoam but any multiphase or multispecies solver. Usually the hEqn looks like:
Code:
    fvScalarMatrix hsEqn
    (
        fvm::ddt(rho, hs)
      + mvConvection->fvmDiv(phi, hs)
      - fvm::laplacian(turbulence->alphaEff(), hs)
    ==
        DpDt
      + source
    );
Why do we have a laplacian(turbulence->alphaEff(), hs)? What enthalpy do we use? Dealing with different species, doesn't the diffusive energy transport has to be driven by the temperature gradient and not by the enthalpy gradient? Could somebody please explain me a little bit what's behind this?

best,
ilya
