NUMERICAL SIMULATION OF THE INTERACTION OF A DUSTY FLOW WITH AN OBSTACLE
ABSTRACT
This work is dedicated to the problems of numerical simulation of supersonic flow with admixture of particles over blunt bodies. A complex mathematical model, governing two-phase flow in the shock layer and heat and mass transfer in the destructing body is presented. The model of two-phase shock layer is based on Euler description of the gas phase and Lagrangian description of the dispersed phase. The full-scaled variant of discrete-element method is used for direct numerical simulation of the particle dynamics. Results of numerical simulation of thermo-erosive destruction of circular cylinder in two-phase flow are presented. Analysis of multiple factors such as interparticle collisions in a flow, particles reflection from streamlined surface, dispersed admixture feedback on carrier phase and influence of changing body geometry due to mass, carrying away, on two-phase shock layer parameters is carried out.
