Diffusivity coefficients in multicomponent systems

[maistral]

Hi. Is anyone aware of a method to estimate diffusivities in multicomponent systems?

Ie. Finding the gas diffusivity coefficient of ethane in an air-methane mixture, or the liquid diffusivity coefficient of acetone in a water-ethanol mixture.

Are you familiar with HCB?

Hi, thanks for replying.

I don't even know what the acronym means, sorry.

Also, there is a summary of the results from Hirschfelder, Curtiss, and Bird in the book Transport Phenomena by Bird et al.
