Diffusivity coefficients in multicomponent systems

  1. Jul 7, 2018 #1
    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.
