Dufour effect
The Dufour effect is the energy flux due to a mass concentration gradient occurring as a coupled effect of irreversible processes. The effect is named after , who studied it in 1872. It is the reciprocal phenomenon to the Soret effect. The concentration gradient results in a temperature change. For binary liquid mixtures, the Dufour effect is usually considered negligible, whereas in binary gas mixtures the effect can be significant.
