A Study of the Nozzle Flow in a Large Arc-Heated Hypersonic Wind Tunnel.

Abstract

The objective of the study was to obtain information about the flow of chemically reacting air that has been heated in a vortex stabilized, high voltage, direct current arc and expanded to hypersonic speeds in a conical nozzle. The inviscid core of the axisymmetric flow in the supersonic section of the nozzle was theoretically analyzed by the method of characteristics for air in chemical and thermal equilibrium. Impact pressure, mass flux, and heat transfer profiles and nozzle-wall static pressures were obtained. Light emissions from the reacting stream were recorded spectroscopically.
