Hi, i am wondering which file cotains the diffusion coefficients of various species. i found some material in the dir liquids of the thermophysical-lib but here quite a few species have the same diffusion coefficient than heptane. so i guess there must be some other places to look but i dont know where?! Any help or experience in this forum? Looking into solvers which should use diffusion coefficents i was even more confused since every laplacian term uses an effictive viscosity coefficient (lam. plus turb. as usual) instead of a diffusion coefficient. Any help would be really appreciated! regards stephan
