Supersonic Ejector-Diffuser Theory and Experiments

Abstract

Only some general conclusions will be drawn in this section since specific conclusions were included in the foregoing sections. The conclusions are: (1) The constant-area ejector flow model and computer program should be adopted as the basis for design and system studies. This model most realistically predicts the operational characteristics of ejector systems. The relationship and correspondence between variable-area and constant-area mixing tube ejectors should be established by both experiment and analysis. (2) The analysis of variable-area mixing-tube ejectors should be continued. (3) The design of potential high-performance ejectors must improve mixing and momentum transfer; some designs with potential are: unsteady flow, periodic pulsating flow, resonance phenomena, and/or various nozzle and mixing-tube geometries. (4) The computer models developed in this study should be augmented and incorporated into an overall system program and further improvement of sub-system models should be continued.
