Anisotropic mass diffusivity
 

I am using a "species transport" model to describe two different gases flowing through a porous medium in an axisymmetric analysis. FLUENT gives you the option of selecting a "mass diffusivity (m2/s)" under "materials->mixture-template". This mass diffusivity term assumes isotropic mass diffusivity. I am interested in separating the radial and axial mass diffusivity terms. Does anyone have any suggestions on how to separate these terms?

Thanks!

Did you follow up with: http://my.fit.edu/itresources/manual...ug/node350.htm

to see if that could help?
