ABSTRACT

Because of the phenomenon of kinetic energy in accumulating supercooled water, crystallization may arise due to both single intensive mechanical action and multiple pulses of low intensity. The results of experimental studies on crystallization of supercooled water have revealed a connection between the parameters of the intermolecular interaction and macroscopic phenomena accompanying the crystallization of the supercooled liquid. A mathematical model of the crystallization and stability criterion of a supercooled liquid when it hits the surface of the aircraft is developed. Numerical and experimental evaluation of the physical parameters characterizing the crystallization of the supercooled liquid in relation to the problem of icing is presented
