Abstract : The primary purpose of Phase II of the ejector study has been to provide experimental data for engineering design purposes. The geometric and state parameters of the ejector were investigated over a wide range, both with and wfthaut diffuser. Variation in the ejector performance was determined for a change in primary temperature, and the effect of the use of a supersonic primary nozzle was also investigated. Comparisons of theoretical and experimental pumping performance without diffuser are presented.
