Unified thermodynamic modelling of diffusion and thermodiffusion coefficients

The paper discusses a new approach to thermodynamic modelling of transport coefficients in mixtures, responsible for diffusion and thermodiffusion. A theoretical framework (A. Shapiro, J. Non-Equilibrium Thermodyn., 45 (2020), 343) expresses these values terms the quantities, penetration distances emission functions, that may be determined thermodynamically. goal present work is verify scheme by application available experimental data on coefficients. consequence theory parameters fitted applied prediction thermodiffusion accuracies fitting verified work. To do so, simplified case binary explicit formula are derived. results indicate good qualitative and, most cases, quantitative behaviour model, although some problems remain.
