On the formation of an external cluster flow in a supersonic jet

Abstract

In this work, the influence of the cluster formation process on the gas dynamics of a supersonic flow is studied by the method of electron-beam visualization. Corrections to the model for describing the transverse dimensions of supersonic flows under conditions of developed condensation are presented. Possible causes and conditions for the formation of a secondary cocurrent flow are analyzed. The influence of background gas penetration into the clastered flow has been studied. The conditions for the occurrence of an anomalous afterglow of a clastered flow upon initiation by an electron discharge are studied.
