%X This paper describes the problems of numerical simulation of supersonic gas-particle flow over blunt bodies. A complex mathematical model is proposed, coupling gas flow in the shock layer, particle advection in the carrying phase, and heat- mass transfer in the body that is being destroyed. The Eulerian description fits best for the gas phase, and the Lagrangian description is most suitable for the dispersed phase. Particle dynamics is fully handled via the discrete-element method. The result is a numerical simulation of the thermoerosive destruction of a circular cylinder in two-phase flow. The authors present an analysis of multiple factors, such as interparticle collisions in a flow, particle reflection from a streamlined surface, dispersed admixture feedback on the carrier phase, and the influence of changing body geometry due to mass entrainment on two-phase shock layer parameters.
