Abstract

We consider the possibility of altering the “choking” conditions of a supersonic gas ejector by installing a cylindrical wall perforated by longitudinal slots in the initial segment of the mixing chamber; this wall is an extension of the high-pressure nozzle. A diagram of the ejector and results of an experimental study of a series of ejectors of various permeabilities for the perforated wall are presented. A comparison is made with the classical ejector, which shows that in several regimes the ejector characteristics may be improved several fold.
