# Consolidated theory of fluid thermodiffusion

@inproceedings{VanBrunt2021ConsolidatedTO, title={Consolidated theory of fluid thermodiffusion}, author={Alexander Van-Brunt and Patrick E. Farrell and Charles W. Monroe}, year={2021} }

We present the Onsager–Stefan–Maxwell thermodiffusion equations, which account for the Soret and Dufour effects in multicomponent fluids by treating heat as a pseudo-component. Unlike transport laws derived from kinetic theory, this framework preserves the structure of the isothermal Stefan–Maxwell equations, separating the thermodynamic forces that drive diffusion from the force that drives heat flow. The Onsager–Stefan– Maxwell transport-coefficient matrix is symmetric, and the second law of…
