Theoretical prediction of thermal diffusion in water-methanol, water-ethanol, and water-isopropanol mixtures using the PC-SAFT equation of state (Q2505113)

This article contains discussion of various models of thermal diffusion of fluid mixtures. .It contains very little information which would be of interest even to applied mathematicians. The authors present various articles written on this subject by prominent chemists. The reviewer recalls Dirac's advice for comparisons of various approaches, different assumptions, and then making corrections to previous corrections after some experiments in problems of physics. This seems to be the situation discussed by the authors. While important physical concepts such as free energy (in this case Helmholtz free energy), or enthalpy, emerge, the predominantly experimental results dominate the authors' predictions. The author sympathizes with the chemists who have to deal with long chains of molecules, and are unable to predict accurately diffusion processes, but somehow no elegant mathematical theory has emerged, and it is not likely to emerge in the near future.
