This lecture covers: Thermo-osmotic and mechano-caloric effects. 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.
