Дослідження рівноважного стану води і двокомпонентноїгазової суміші сухого повітря та водяної парипри поверхні розділу фаз в умовах фазового перетворення Частина II

Abstract

In this part of the paper, a new phenomenological approach to the description of the phase transformation of a liquid into a two-component gas mixture is proposed on the basis of the distribution function of the investigated macroscopic physical quantity from the thermodynamic variables (parameters) of the system. The equivalence of the mechanical and energy characteristics of the thermodynamic equilibrium on the interface between the liquid and gas phases is demonstrated. The conditions of the phase equilibrium between a liquid and a gas mixture at the superficial layer under conditions of evaporation or condensation are recorded. By the graphical methods the relative changes (displacement or fluctuations) of thermodynamic quantities in the phase transformation are depicted. In the model approximation, distortion of the meniscus for surface of the phase separation between the liquid and gas phases is calculated according to the balance (equilibrium) relations.
