Description
Description: Thermal diffusion or Soret effect is a phenomenon of mass transport in fluid mixtures driven by temperature gradients. In this paper, we have studied thermal diffusion coefficients for different binary n-alkane mixtures (equal mass fraction) through both theoretical and experimental methods. The theoretical model is based on the irreversible thermodynamics. Particularly, the nonequilibrium thermodynamic property τ is examined and remodeled with a consideration of vapor-liquid equilibrium in binary mixtures. The experimental method is based on the thermogravitational technique. The new model provides a good agreement with the experimental data from this study and in the literature.
