Effect of solid thermal conductivity and particle-particle contact on effective thermodiffusion coefficient in porous media [PDF]
, 2011 Transient mass transfer associated to a thermal gradient through a saturated porous medium is studied experimentally and theoretically to determine the effect of solid thermal conductivity and particle-particle contact on thermodiffusion processes.

Thermodiffusion in binary liquids: the role of irreversibility [PDF]
, 2013 We study thermal diffusion in binary mixtures in the framework of non-equilibrium thermodynamics. Our formal result displays the role of partial enthalpies and Onsager's generalized mobilities.

Theory and application of “smart mold powders” for continuous casting of steel
工程科学学报, 2022 The success of the continuous casting process is inseparable from the correct use of mold powders. However, fluoride volatilization and the contradiction between slag entrapment, heat transfer, and lubrication that occurs in the mold restrict the ...

Analytical and numerical stability analysis of Soret-driven convection in a horizontal porous layer [PDF]
, 2007 We present an analytical and numerical stability analysis of Soret-driven convection in a porous cavity saturated by a binary fluid. Both the mechanical equilibrium solution and the monocellular flow obtained for particular ranges of the physical ...

Effects of second diffusing component and cross diffusion on primary and secondary thermoconvective instabilities in couple stress liquids [PDF]
, 2017 Linear and weakly nonlinear analyses are made for the Rayleigh-B´enard convection in two-component couple-stress liquids with the Soret effect. Conditions for pitchfork, Hopf, Takens-Bogdanov, and codimension-two bifurcations are presented.

Soret Effect in a Nonionic Surfactant System [PDF]
, 2006 We studied the thermal diffusion behavior of C10E8 (decyl octaethylene glycol ether) in water by means of thermal diffusion forced Rayleigh scattering (TDFRS). We determined the two diffusion coeffi- cients D T, D and the Soret coefficient S T in a concentration range from w = 5 wt% to 25 wt% in a temperature range from T = 20 °C to 40 °C. The obtained
