Air Ejector

The performance and flow field characteristics for two-dimensional ejector systems are determined theoretically for the condition when operation is independent of ambient pressure. The method considers the detailed inviscid interaction between the primary and secondary streams within the mixing tube and an estimate is made of the secondary flow entrained by the two-stream viscous mixing region. The validity of the theory is tested by comparing the performance characteristics of an experimental ejector facility with theoretical predictions and by comparing the theoretical flow field, in terms of constant density contours, with infinite fringe interferograms.

Abstract This paper reports the results of an investigation in which the authors studied the performance of the simplest form of ejector which would function in a useful manner. An attempt was made to analyze the data as nearly independent of other work on ejectors as possible, and to compare the performance with that predicted analytically. The primary purpose of the study was to test the utility and validity of a method of analysis, and not to devise a new type of ejector.
