Dear Foamer,

I am currently working on reactingFoam without reactions.
I met a problem with the muEff. I have two kinds of gases, propane and air (N2 and O2), the viscosity of these species are different. And I check in the reactingFoam solver, in the YEqn, we have a function like this:

fvm::ddt(rho, Yi)
+ mvConvection->fvmDiv(phi, Yi)
- fvm::laplacian(turbulence->muEff(), Yi)

could I ask where does the muEff() here comes from?
or does anyone know in reactingFoam how the viscosity is considered.

Thank you

Best Regards
