FURTHER STUDIES OF THE JET COMPRESSOR

Abstract

A description is given of the various regimes of flow that can exist in the jet compressor. A new apparatus is described and data taken with it on 6 systems of gases (He:Freon-113, He:air, air:Freon-113, air:Freon-12, air:air, and Freon-12:air) are presented. The highest efficiency achieved with the new apparatus is 0.125, at a compression ratio of 1.590, with helium as the driven gas and Freon-113 as the driving gas. Calculations of momentum-flux balance within the jet compressor are made, with allowances for friction, and, when necessary, for flow separation within the driving-gas nozzle. The changes of available energy associated with the various processes that take place within the jet compressor are individually calculated from the experimental data. The flow rate of driven fluid is calculated as a function of inlet pressure for the system air:Freon-113, by a method pro posed by Fabri and Siestrunck; the results rep resent the observations, but not accurately.
