The condition for the conservation of momentum at the interface under phase transitions of solutions
Abstract. The present work considers a change in the momentum under the transfer of a solution through the interface. It is shown that pressure related to the partial volumes of components arises in a solution under diffusion. As a result, the distribution of the concentration of solution components differs qualitatively from the known solutions. In contrast to the description of one-dimensional interphase mass transfer using the convective diffusion problem, the proposed model provides the stationary exponential distribution of components in both phases. The model describes component segregation by the interface, observed in the experiments.
