Experimental Investigation of the Effects of Tip Clearance and End Losses on Axial Compressor Performance.

摘要

The objective of the study was to determine by experimental means the rotor efficiencies at different radii between hub and tip of a single stage axial compressor at its design point,to show the influence of tip clearance and end losses. Procedures for calibration and application of pressure probes to survey the flow in the compressor were established and programs were written to analyze the measured data. Recommendations are made for improvements of the data reduction method,which should precede experiments involving controlled changes in the blade tip clearances. (Author)
