Abstract

The role of hot gas-vapor-droplet flows in promising technologies is enhanced. They are such technologies as constructing technologies of heat carriers based on the stack effluents, droplets and vapors of water; thermal or flame purification of liquids, emulsions and suspensions; processing the sluggy thermally loaded surfaces of power equipment; defrosting the granular medium; polydisperse extinguishing. The periods of heating or cooling various surfaces can be significantly minimized by hot gas-vapor-droplet flows. The work presents the investigation results of the evaporation features of water droplets while they're moving through hot combustion products of typical liquid flammable substances by the Shadow Photography and Interferometric Particle Imaging methods. The integral characteristics of motion and evaporation are defined. Initial sizes of droplets and temperatures of combustion products are varied within wide ranges: 0.05-4 mm and 400-1900 K. The conditions, under which it is possible almost completely or fairly moderate (with minimal change in mass of the liquid) evaporation of droplets under intense heat, are determined.
