Detailed Description

Diffusive fluxes of a gas mixture on every face (one-point rule), added to face_flux (momentum and energy) and to the species slots of side 0 (as mass leaving cell 0).

Face values and gradients of u, T and X_k average the two cells' and correct their component along the line between the centroids, as ViscousFluxFunctor; the transport coefficients are the averages of the two cells'. Species fluxes are the mixture-averaged ones with a correction velocity, as Cantera's (Kee, Coltrin & Glarborg): j_k = -rho D_k (W_k / W) grad X_k + Y_k sum_j rho D_j (W_j / W) grad X_j, with Y at the face normalized, so that sum_k j_k = 0 to round-off and rho needs no diffusion term; with thermal diffusion, j_k also has the Soret flux -D^T_k grad T / T (the D^T_k sum to zero, as Cantera's), with the face's T, gradient and averaged D^T_k. The energy flux carries sum_k h_k j_k. Walls and symmetry planes carry no heat or species flux (adiabatic, non-catalytic); transmissive faces take their image face's values, gradients and coefficients; outflow faces and transmissive faces without an image have zero normal derivatives; UPT faces take the cell's values and gradients.
