New Possibilities of the Electron Beam Method for Diagnostics of High-Temperature Supersonic Gas Stream of Complicated Molecular Composition

Abstract

Today the electron beam diagnostics is one of the main methods for investigation of rarefied gas flows allowing to determine a number of local gas parameters such as density partial concentration temperatures of internal degrees of freedom etc. The relation between the intensities excited by electron beam spectra and local gas parameters is provided either theoretically or by a calibration curve. The aim of the present paper is an analysis of the possibilities of electron-beam diagnostics for partial density measurements of high temperature rarefied gases and their mixtures applying to the mixtures of N2 + CO2.
