Dufour and Soret Effects on Square Porous Annulus [PDF]
Advances in Mechanical Engineering, 2014 A study on heat and mass transfer behaviour on porous medium embedded in a square annulus is conducted. The inner surface wall is considered to have a cool temperature T c while the outer surface is exposed to a hot temperature T h .

Influence of the Dufour effect on convection in binary gas mixtures [PDF]
Physical Review E, 1995 Linear and nonlinear properties of convection in binary fluid layers heated from below are investigated, in particular for gas parameters. A Galerkin approximation for realistic boundary conditions that describes stationary and oscillatory convection in ...

Thermal Diffusion Factor in Gas Mixture-Dufour Effect (I) [PDF]
Iranian Journal of Chemistry & Chemical Engineering, 1991 The thermal diffusion factor, aT, for a binary gas mixture is calculated on the basis of nonequilibrium thermodynamics. A new formula for aT is derived and this factor is given for several paris of gases according to this formula.

Bulletin of the Chemical Society of Japan, 1975 Abstract A study of the Dufour effect was made for five different gas mixtures: H2–N2, H2–O2, H2–N2O, He–N2O and He–O2. Measurements were made at 25 °C under 700 Torr. The values of the thermal diffusion factor were calculated for the above mixtures from the experimental data on the basis of the thermodynamics of irreversible processes.

A Numerical Implementation of the Soret Effect in Drying Processes [PDF]
, 2020 Drying of porous media is strictly governed by heat and mass transfer. However, contrary to the definition that drying is simultaneous transport mechanisms of heat and mass, most past and current models either account for temperature or concentration ...

Diffusion Thermoeffect in Gases (The Dufour Effect) [PDF]
Bulletin of the Chemical Society of Japan, 1979 Abstract A study of the Dufour effect was made for four different gas mixtures: SF6–N2O, SF6–N2, SF6–CO2, and He–CO2. Measurements were made at 300 K under 700 Torr. The values of the thermal diffusion factor were calculated for the above mixtures from experimental data on the basis of the thermodynamics of irreversible processes.
