Comment on “Role of the velocity frame of reference in thermodiffusion in liquid mixtures” by M. Eslamian, C.G. Jiang and M.Z. Saghir

Abstract

We analyze the material transport equations (MTE) derived by Eslamian and co-authors and address the criticism expressed regarding the approach formulated in our previous work. In doing so, we show that the MTE formulated by Eslamian and co-authors are valid only in closed stationary non-isothermal systems in combination with the restrictions on the Onsager coefficients formulated in our work which is criticized, and that for non-stationary systems the approach we took can be used.

Keywords:
