Dear all
I am working on a reacting flow simulation using reactingFoam, which is basically built on a unity Lewis number formulation. Since I have laminar flow, this assumption is a complete no no and I need at least a Mixture averaged transport (a multicomponent transport would be the best). I saw a long thread going on where there is a multicomponent transport library-

Multi species mass transport library [update]

but this one has some errors that nobody has yet solved to my knowledge. Could anyone PLEASE share your thoughts if you added (or trying to add) any transport (Mixture averaged or multicomponent) in your simulation. I would highly appreciate your kind cooperation.

I have the same problem with you. In reactingFoam,transport is defined as turbulence->muEff() (mass diffusion). But i can't find how it is calculated in the code.
