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.

Numerical Investigation on the Heat and Mass Transfer in Microchannel with Discrete Heat Sources Considering the Soret and Dufour Effects

Micromachines, 2022
Heat-transfer enhancement in microchannel heat sinks (MCHS) has been a hot topic in the last decade. However, most published works did not focus on the heat sources that are discrete, as in most microelectronic devices, and the enhancement of heat and ...

Dufour Effect in Gases [PDF]

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.
