ON RELATING THERMODYNAMIC DIFFUSION COEFFICIENTS WITH PHENOMENOLOGICAL COEFFICIENTS IN BINARY SYSTEMS

摘要

A relation between the thermodynamic diffusion coefficients (D_1(mu)) and the phenomeaological transport coefficients (Ltp has been derived for binary systems. The relation is similar to the relation between tracer diffusion coefficient, Di and the phenomenological coefficients, Lt,. This shows the equivalence between thermodynamic intrinsic diffusion coefficient and tracer diffusion coefficient.
