Abstract
A general theoretical framework to address the coupled heat-mass transport and predict the corresponding Soret and Dufour coefficients is presented. It is shown that by starting from microscopical definitions of heat and mass currents, conservation laws dictate the form of the differential equations governing the time evolution of the temperature and mass density profiles along the sample. The present theoretical device is finally validated using as benchmark system a two-component Lennard–Jones (LJ) liquid system, for which generalized diffusivities are estimated in different reduced temperature and density regions of phase diagram.File | Size | Format | |
