NUMERICAL SIMULATION OF HEAT TRANSFER AND THERMO-EROSION DESTRUCTION OF A BLUNT BODY IN A SUPERSONIC DUSTY FLOW
ABSTRAKT
This work is dedicated to the problems of numerical modeling of supersonic flow with an admixture of particles over blunt bodies. A complex mathematical model, including a model of two-phase flow in a shock layer and a model of heat and mass transfer in the destructing thermal protection coating is presented. The model of the two-phase shock layer is based on combination of an Euler description of the gas phase and a Lagrangian description of the dispersed phase. In so doing we use the full-scaled variant of the discrete-element method, i.e. it performs direct numerical modeling of the admixture dynamics. The effect of collisional and collisionless particle admixture on the flow of the carrying gas and convective heat transfer is studied as well as the direct impact of the two-phase flow on the streamlined body.
