RISVisualization and Time Resolved Particle Image Velocimetry Measurements of the Flow in the Tip Region of a Subsonic Compressor Rotor
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A new optically index matched facility has been constructed to investigate tip flows in compressorlike settings. The blades of the one and a half stage compressor have the same geometry, but lower aspect ratio as the inlet ...
Experimental Investigation of the Role of Large Scale Cavitating Vortical Structures in Performance Breakdown of an Axial Waterjet Pump
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Flow phenomena and mechanisms involved in cavitation breakdown, namely, a severe degradation of pump performance caused by cavitation, have been a longstanding puzzle. In this paper, results of highspeed imaging as well ...
Experimental and Analytical Assessment of Cavity Modes in a Gas Turbine Wheelspace
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Fast response pressure data acquired in a high-speed 1.5-stage turbine hot gas ingestion rig (HGIR) show the existence of pressure oscillation modes in the rim-seal-wheelspace cavity of a high pressure gas turbine stage ...
