A realization of the discrete-element method for numerical modeling of two-phase flow of gas- particle mixture is developed. One modeling particle corresponds to one real particle. Particle reflection from body surface, particle rotation and inter-particle collisions are taken into consideration. Numerical simulation of the supersonic two-phase flow over a circular cylinder is carried out. The results are presented to illustrate the influence of inter-particle collisions and particle rotation on parameters of body-flow interaction.
