Abstract: Relatively small stable flow ranges experienced on some high Mach number centrifugal compressors, triggered by the inability of stationary vaned diffusers to operate at flows below their maximum ...

Abstract: Test results pertaining to the stalling characteristics of centrifugal compressor impellers with parallel wall vaneless diffusers are presented and studied to correlate the coincidence of stall ...

Abstract: This paper describes the development of a subscale single-stage centrifugal compressor with a dimensionless specific speed (Ns) of 1.8, originally designed for full-size application as a high ...

Abstract: This paper describes experiments that were conducted several years ago on a single-stage open-face centrifugal partial emission compressor with a nondimensional specific speed of 0.15 (19.3 ...

Abstract: This paper describes the results of compressor rig testing with a moderately high specific speed, high inducer Mack number, single-stage centrifugal compressor, with a vaned diffuser, and adjustable ...

Abstract: The technology of high-pressure air or hot-gas impingement from stationary shroud supplementary nozzles onto radial outflow compressors and radial inflow turbines to permit rapid gas turbine ...

Abstract: Starting torque characteristics of small self-sufficient gas turbine engines often present a belated problem to the development engineer, particularly when proceeding into final engine qualification ...
