Connection between thermophoresis and thermodiffusion in a liquid binary mixture
Résumé
In a liquid suspension, thermophoresis is the motion of a suspended particle under a temperature gradient. In a liquid binary mixture, thermodiffusion is the generation of a composition gradient upon application of a temperature gradient. In this paper, a quantitative connection is established between the two phenomena without making assumptions about their mechanisms. It is shown that Galilean invariance and the choice of a Galilean reference frame play a key role in that connection. Our results are not restricted to very dilute suspensions or mixtures.
