Abstract Mathematical models of nonspherical particles’ motion in nonuniform flow were proposed for continuous flow approach as well as for single particles’ motion simulation. Lagrangian approach was used to simulate aerosol flow with nonspherical particles around transversal cylinder. Peculiarities of supercooled water crystallization were investigated via cryostat, infrared spectroscopy, and original devices for supercooled droplets’ impact simulation. The results of the experimental study of the supercooled water crystallization are presented. The relationship between the parameters of intermolecular interaction with the parameters of macroscopic phenomena accompanying the crystallization of supercooled water was determined. Mathematical models of the supercooled liquid crystallization and the expression for the minimum rate for the beginning of the supercooled droplets crystallization on impact with the surface of the aircraft were developed. The numerical and experimental evaluations of physical parameters characterizing the supercooled liquid crystallization in the icing problem are performed. Two-phase boundary layer formation near nanostructutred surface was investigated via molecular dynamics method.
