Investigation of the Supersonic-Supersonic Ejector,

Abstract

An investigation of the constant area, supersonic-supersonic ejector has been conducted wherein one supersonic stream is pumped directly by another inside a confining duct. The theoretical analysis is based on simplified, one-dimensional models of the constant area mixing section and inviscid interaction region. The parametric dependence of the ejector pressure recovery performance on each of seven dimensionless variables is presented. A series of small scale, axisymmetric ejector experiments indicates that the theory predicts maximum ejector compression ratios which are 15 to 22 percent higher than the measured values and that the ejector is susceptible to separation of the secondary stream at the confluence point of the primary and secondary streams.
