DOWNLOAD EBOOKMost naturally occurring fluids are multicomponent mixtures. Nevertheless, measured diffusion coefficients are almost exclusively for binary mixtures. Even for ternary mixtures, data is extremely limited. Molecular diffusion is fundamentally different in multicomponent than in binary mixtures due to cross molecular diffusion. All diffusion coefficients are non-trivial functions of composition, temperature, and pressure. Consequently, ternary diffusion coefficients cannot be obtained from binary data.
