Two-phase shock layer in a supersonic dusty gas flow

Abstract

The problems of the numerical simulation of a dusty supersonic flow past a blunt body is examined. The model of a two-phase shock layer is presented. The Euler description of the gas phase and the Lagrange description of the dispersed phase that is used in combination is the basis of the present model. The complete variant of a discrete-elemental method, i.e., the direct numerical simulation of a dynamic admixture, is used. The effect of collisional and collisionless foreign particles on to the carrying gas flow and heat transfer is studied, as well as the direct impact of a two-phase gas flow onto a streamlined surface, by considering particle collisions and the dispersed phase’s reverse impact on the gas phase.
