The Journal of Chemical Physics, 1973
Equations for the Dufour effect, which is the development of a temperature gradient due to diffusion, have been solved for geometrically well-defined cells which have either all walls adiabatic or adiabatic lateral walls and diathermic ends. Two self-consistent, well-ordered perturbation schemes have been used, and heat of mixing, variability of all ...

Physica A: Statistical Mechanics and its Applications, 1979
Experiments have been performed to study the influence of a magnetic field on the Dufour effect (or diffusion-thermo effect) in an equimolar N2Ar mixture at room temperature. By comparing these experimental results with those obtained previously for the field effect on the thermal diffusion, an Onsager relation between these field effects is confirmed.

Dufour Effect in Liquid Mixtures
The Journal of Chemical Physics, 1969The Dufour effect in the liquid state has been investigated for 10 systems. Dufour coefficients have been estimated from the experimental data. The values of Dufour coefficients have been compared with those for thermal-diffusion coefficients estimated from the known data on the soret coefficient using measured values of diffusion coefficients recorded

The Dufour Effect in Film Cooling Experiments With Foreign Gases
Journal of Thermal Science and Engineering Applications, 2021Abstract In typical film cooling experiments, the adiabatic wall temperature may be determined from surface temperature measurements on a low thermal conductivity model in a low-temperature wind tunnel. In such experiments, it is generally accepted that the adiabatic wall temperature must be bounded between the coolant temperature and ...

Pressure Dependence of the Diffusion Thermoeffect in Gases (Dufour Effect)
The Journal of Chemical Physics, 1967A modified Loschmidt apparatus for the measurement of the diffusion thermoeffect as a function of pressure is described. Measurements are reported for H2–Ar, H2–CO2, and H2–CH4 for pressures between 1 and 20 atm at room temperature. The experimental results have been explained semiquantitatively in terms of the pressure dependence of the relevant ...

Soret‐Dufour effects in electroosmotic biorheological flow of Jeffrey fluid
Heat Transfer, 2020AbstractThe Soret and Dufour cross‐diffusion on the electrokinetic flow of Jeffrey fluid augmented with peristalsis have been presented. The fundamental equations are employed to predict the mass distribution in the two‐dimensional asymmetric electroosmotic channel.

Radiative three-dimensional flow with Soret and Dufour effects
International Journal of Mechanical Sciences, 2017Abstract This article explores Soret and Dufour effects in magnetohydrodynamic three-dimensional (3D) flow of second grade fluid. Flow is induced due to an exponentially stretching surface. The energy and concentration equations are modeled in the presence of thermal radiation and Soret and Dufour effects.

Dufour effect in superionic copper selenide
Physics of the Solid State, 1998The Dufour effect has been observed in the superionic conductor copper selenide, Cu2−xSe. This effect is the opposite of the Soret thermal diffusion effect which was previously only observed in gaseous and liquid systems.
