摘要

质量扩散和热扩散是流体混合物中的传输现象，在许多应用中都很重要。本文认为，鉴于波动流体力学中的一些惊人发现，这些输运现象甚至变得更加有趣，从而可能导致非平衡热力学中新出现的问题。本文简要回顾了这一主题的历史。然后，论文探讨了传统质量和热扩散系数取决于参照系的问题。本文阐明了这一问题的简单解决方案。

Mass and Thermodiffusion in Non-equilibrium Fluctuating Hydrodynamics

Mass and thermodiffusion are transport phenomena in fluid mixtures important in many applications. In this paper it is argued that these transport phenomena have even become more interesting in view of some surprising discoveries from fluctuating hydrodynamics leading to possible new emerging issues in non-equilibrium thermodynamics. A short review of the history of this subject is presented. The paper then addresses the problem that the conventional mass and thermodiffusion coefficients depend on the frame of reference. A simple solution to this problem is elucidated.

期刊介绍： International Journal of Thermophysics serves as an international medium for the publication of papers in thermophysics, assisting both generators and users of thermophysical properties data. This distinguished journal publishes both experimental and theoretical papers on thermophysical properties of matter in the liquid, gaseous, and solid states (including soft matter, biofluids, and nano- and bio-materials), on instrumentation and techniques leading to their measurement, and on computer studies of model and related systems. Studies in all ranges of temperature, pressure, wavelength, and other relevant variables are included.
