Abstract:

The critical operating conditions of an ejector with a cylindrical mixing chamber are analyzed within the framework of ideal-gas dynamics. Jet flows, overexpanded with respect to the static pressure of a low-pressure gas, are calculated on the basis of supersonic compressed layer theory. The calculations confirm the experimental finding that the degrees of compression attainable in ejectors in the presence of large pressure gradients exceed the limiting analytical values obtained from theories developed for moderate pressure gradients.
