The Development Peculiarities of Gas-Dynamic Processes of a Pulsing Gas Flow in a Dense Layer

Abstract: Based on the analysis of physical regularities of changes in hydrodynamics of a system of composition of layered components in a dense blown layer, the regularities of development of pressure changes in the flow of a pulsating blast with a given frequency of pulsations are established. The main regularities of pressure change in the pulsator as well as in the targeted object of periodic oscillations of gas flow supply are theoretically determined. The features of the change in the force effects of the pulsating flow are shown as the sum of intermediate time effects, which are capable of providing an increase in the rate of filtration of gases through the layer packing while reducing its gas-dynamic resistance. © 2021, Allerton Press, Inc.
