RISInvestigation of Blade Vibration of Radial Impellers by Means of Telemetry and Holographic Interferometry
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: On a high-pressure, high-mass flow, centrifugal compressor blade vibration measurements are carried out to determine the excitation mechanism in various operating ranges. For these experiments ...
Comparisons of the Relative Effect of Tip Clearance on Centrifugal Impellers
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Why do some centrifugal impellers exhibit high sensitivity to tip clearance losses while others don’t? This may be understood by considering the geometric and fluid mechanics design parameters ...
Analysis of Measurements in Vaned Diffusers of Centrifugal Compressors
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In vaned diffusers of centrifugal compressors many different flow phenomena interfere with one another, and different geometric parameters influence the flow field. Variations of these parameters ...
Blade Vibration Measurements on Centrifugal Compressors by Means of Telemetry and Holographic Interferometry
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Blade vibration measurements have been carried out on a high-pressure, high mass-flow centrifugal compressor to determine the excitation mechanism. For the experimental investigation, semiconductor ...
A Distinction Between Different Types of Stall in a Centrifugal Compressor Stage
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The flow at the stall line of a centrifugal compressor with vaneless diffuser was investigated at different speeds. A distinction between three kinds of stall phenomena could be made. One type ...
The Vortex-Filament Nature of Reverse Flow on the Verge of Rotating Stall
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: On the verge of rotating stall, very orderly reverse flow forms from the outlet of the rotor/impeller along the casing/shroud toward the inlet in axial/centrifugal compressors (Koch, 1970; Haupt, ...
On the Mechanism of Dangerous Blade Vibration Due to Blade Flow Interactions on Centrifugal Compressors
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Severe blade flow interactions at part-load operation conditions were investigated on a centrifugal compressor with a vaned diffuser leading to material stresses beyond the allowable values. By ...
Discussion: “Rotating Waves as a Stall inception Indication in Axial Compressors” (Garnier, V. H., Epstein, A. H., and Greitzer, E. M., 1991, ASME J. Turbomach., 113, pp. 290–301)
Publisher: The American Society of Mechanical Engineers (ASME)
Matching of Turbocomponents Described by the Example of Impeller and Diffuser in a Centrifugal Compressor: Part I—Aerothermodynamic Coupling of Impeller and Diffuser. Part II—Optimized Stage Efficiency of a Centrifugal Compressor
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An important task in the design of turbo machinery is the determination of the aerothermodynamic parameters necessary to assure optimum matching of the individual compressor components. With ...
Blade Excitation by Broad-Band Pressure Fluctuations in a Centrifugal Compressor
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The mechanism of blade excitation during the operation of a high-mass-flow, high-pressure-ratio centrifugal compressor has been investigated. This was carried out in the compressor operating range ...
