Evaporation of droplets in a two-component flow
Abstract
The interaction of a two-component flow with a single droplet is examined. The problem is formulated as the problem of heat exchange between a sphere and an external medium in the presence of a variable negative internal heat source and boundary conditions of the second kind. Expressions describing the dependence of the lifetime of the droplet on the rate of flow and temperature are derived. The intensifying effect of solid particles on evaporation is investigated. Theoretical and experimental results show that there exists a critical concentration of the solid component at which the intensifying mechanism changes, although strictly speaking agitation of the vapor boundary layer around the droplet and disintegration of the droplet itself occur at any concentration of the third component.
