I want to know how I can get the molecular diffusivity of a component in the mixture from pordif.f subroutine
The point is, I want to take the molecular diffusivity calculated by the starcd and then modify the value for the porous domain, How can I do that?
I had a similar question of modelling species diffusivity in porous media. I'll be curious to know if you find out anything interesting from this discussion.
I use STAR CCM+ extensively and had talked to Adapco regarding this. They do not have anything in STAR CCM+ that can model the diffusivity. But I'd be glad to know if this can be worked with in STAR CD.
