Diffusivity of impure CO2

  Hi,
  I am trying to model the diffusion of impure CO2 ( containing either N2 or SO2) in water. However, since this is a ternary system, it is essential I specify the effective diffusivity of the species ( CO2 and SO2) in water. I will appreciate any idea on how to specify this using either a UDF or other methods in Fluent.
  Thank you.

  Have a look at the multicomponent diffusivity - does that do what you need?
