An Investigation of Planar, Two-Dimensional Ejectors with Periodic or Steady Supersonic Driver Flow,

Abstract

The results of an experimental and theoretical investigation of a planar, two-dimensional constant area ejector with a periodically pulsed or a steady, supersonic driver flow will be presented. The purpose of this investigation was to determine the potential of using unsteady flow techniques to enhance the mixing between high-speed streams interacting within a duct and to improve the overall pressure recovery obtained within an ejector system. This research was motivated by mixing problems which were encountered in high-energy chemical laser systems at the laser fuel-oxidizer nozzle array and within the ejector-diffuser system required to pump the laser effluent for atmospheric discharge.
