FLOW AROUND A SOLID BODY OF THE HEATED SUPERSONIC GAS-DISPERSED JET WITH ACCOUNT OF THE ROTATION OF THE REJECTED PARTICLES
要約
A physico-mathematical model of a particle-carrying gas interaction taking into consideration the Magnus force, experimental data on the mutual influence of the particle linear motion and spinning, the finite time of particle heating, and the cutoff of its heat radiation spectrum, is developed. The carrying gas dynamics is described within the framework of the Euler approach, with heat radiation of the gas and solid body being neglected, as well as erosion of this body. A wide range of particle dimensions is investigated numerically, in which various regimes of the particle-body surface interaction are implemented (adhesion, rebound, absolutely inelastic collision). The influence of the particle self-radiation on their heat exchange is evaluated. These algorithms allow calculation of the mass, momentum, and energy flow densities carried by the particles upon an axisymmetric body surface that is streamlined, in particular, by a two-phase jet.
