Interdiffusion in a binary mixture, Maxwell-Stefan and Fick diffusion coefficients. Thermophoresis: Soret and Dufour effects. Multicomponent heat, mass, and charge transport.Instructor suggests to set viewing speed at 1.5 for faster learning.Slides for this lecture: https://ocw.mit.edu/courses/2-43-advanced-thermodynamics-spring-2024/resources/mit2_43_s24_lec25_pdf/Key moments:00:00:00 - Introduction00:00:19 - Onsager Cross Effects and Curie Symmetry Principle00:00:55 - Relation Between Independent Diffusive Fluxes00:01:51 - Relative Diffusive Fluxes and Forces00:04:43 - Cross Effects Between Vectorial Fluxes and Forces00:12:34 - Thermoelectric Effects00:13:06 - Second-Law Efficiency of Thermoelectric Generator00:22:46 - Thermo-Osmosis of Pure Substances in Porous Media00:29:39 - Interdiffusion of Two Constituents00:38:38 - Thermodiffusion Effects.
