Abstrakt:	A physical and mathematical model of the movement of nonspherical particles in the two-phase flow over an aerodynamic body, allowing one to estimate the area of wetting of the body surface by these particles depending on their stochastic orientation in the flow, is proposed. On the basis of the heuristic model developed earlier, the coefficients of restoring the velocity components of the ice crystals colliding with the surface of a blunt-nosed body were calculated for values of the governing parameters of the collision process varying within a wide range. It is shown that the initial orientation of these crystals in the aerosol flow over the body influences the trajectories of their movement in the vicinity of the body. [ABSTRACT FROM AUTHOR]
