Abstract

A kinetic model of droplet evaporation in an air-plasma flow is developed. Patterns of the influence of the initial air-plasma flow and droplet parameters and of the initial mass ratio of liquid and gaseous phases on the evaporation kinetics of droplets dispersed in aqueous-organic compositions in the air-plasma flow are established. It is shown that for aqueous-organic compositions having the adiabatic combustion temperature no less than 1200°C, the stage of solvent (water) evaporation is the limiting stage of the whole process in the air-plasma flow.
