Numerical Investigation of the Pulse Jet Flow of an Inhomogeneous Gas-Dispersed Mixture

Abstract

The paper presents the results of numerical simulation of the initial stage of the pulsed inhomogeneous flow of a gas-dispersed mixture as a prototype of the jet powder technology of fire extinguishing or pollution neutralization. New physical effects of a pulsed inhomogeneous jet are revealed: the simultaneous existence of anomalous subsonic and supersonic shock-wave structures, as well as a resonant increase in the mass flow rate of the mixture compared with a homogeneous flow.
