High Temperature Aims and scope

Abstract

Results are given of experimental investigations of basic microscopic parameters of plasma of a longitudinal-and-transverse dc discharge in a supersonic wind tunnel with a backward-facing step. The results of measurements of electric field E, of temperatures of gas T g and of excitation of electron levels T e , and of reduced electric field E/N are compared with the measured or previously found parameters of transverse and longitudinal discharges in supersonic flows and in stationary air in a wide range of pressures and currents.
