要約

The purpose of this work is to develop the physicomathematical model and numerical code for investigation of a monodisperse supersonic flow impinging on a solid axisymmetric body in the case of the large initial mass fraction of particulates. In such flows, a chaotic layer which can be described by the diffusion model arises on the surface of the body in flow. Several variants of the radial distribution of the particle concentration at the nozzle entrance are investigated (these distributions depend on the particulate kinetics in the mixing chamber and serve as a separate problem). The influence of particle substance and dimensions on the flow gas thermodynamics is investigated for a large range of initial values of the particle mass density.
