Résumé

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. 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.
