TL;DR: In this article, the authors modeled the transport phenomena in a multiphase solid matrix packed-bed heat exchanger with the help of the continuum theory of mixtures, which allows a thermodynamically consistent local description.

TL;DR: In this paper, the diffusion coefficients of impurities near the melting points of host substances are estimated from experimental data reported in the literature and the purification efficiency is demonstrated to depend on the shape of the growing crystals.
Abstract: Assumptions sufficient to develop a general model of diffusion and crystallization mass transfer in a countercurrent crystallization column are formulated. The purification efficiency is demonstrated to depend on the shape of the growing crystals. The diffusion coefficients of impurities near the melting points of host substances are estimated from experimental data reported in the literature.

TL;DR: In this article, a mathematical model of the evaporator of a heat pump with carbon dioxide as a working medium and water as a heat-transfer medium is constructed and used to calculate the hydrodynamic and heat-and mass-transfer processes in boiling liquid convection, liquid film evaporation, film breakup, drop settling, and disperse flow.
Abstract: A mathematical model of the evaporator of a heat pump with carbon dioxide as a working medium and water as a heat-transfer medium is constructed and used to calculate the hydrodynamic and heat-and mass-transfer processes in boiling liquid convection, liquid film evaporation, film breakup, drop settling, and disperse flow. The coupled heat transfer between the working medium and the heat-transfer medium in a countercurrent evaporator is considered. The calculation results are compared with the experimental data.
