Abstract :
Formulae for heat and mass exchange from the surface of ice particles of different forms are derived. Destruction of plate, cylindrical and spherical particles in the sublimation regime, as well as the subsequent melting (cylinder, disk) and evaporation of the water droplet formed are investigated. The study was conducted for the parameters averaged over the particle volume: heat release intensity, temperature, evaporation efficiency, etc. Heating time, melting time, evaporation time, evaporation efficiency, temperature for particles in the form of thin long cylinder is presented versus the intensity of laser radiation at various temperatures and pressures of the surrounding air. The results are compared with the correspondent evaporation parameters of a supercooled spherical water droplet.
