Influence of Homogeneous Nucleation on the Intensity of Evaporation/Condensation Processes
Abstract
An approach based on the direct numerical solution of the Boltzmann kinetic equation is proposed to take into account the influence of homogeneous nucleation on the mass transfer intensity in the evaporation/condensation (recondensation) problem. On the basis of the comparison between the scales of the formation time of a critical-size droplet and the time of supersaturation propagation, it is shown that it is possible to describe the considered problem in two stages, i.e., without taking into account the influence of droplets at the first stage and with taking into account their influence at the second stage. The calculation results show that, in the case of immobile droplets, there is a strong influence of bulk condensation on the intensity of the evaporation/condensation process.
期刊介绍：
Colloid Journal (Kolloidnyi Zhurnal) is the only journal in Russia that publishes the results of research in the area of chemical science dealing with the disperse state of matter and surface phenomena in disperse systems. The journal covers experimental and theoretical works on a great variety of colloid and surface phenomena: the structure and properties of interfaces; adsorption phenomena and structure of adsorption layers of surfactants; capillary phenomena; wetting films; wetting and spreading; and detergency. The formation of colloid systems, their molecular-kinetic and optical properties, surface forces, interaction of colloidal particles, stabilization, and criteria of stability loss of different disperse systems (lyosols and aerosols, suspensions, emulsions, foams, and micellar systems) are also topics of the journal. Colloid Journal also includes the phenomena of electro- and diffusiophoresis, electro- and thermoosmosis, and capillary and reverse osmosis, i.e., phenomena dealing with the existence of diffusion layers of molecules and ions in the vicinity of the interface.
