    Abstract

    A high-pressure ratio centrifugal compressor stage consisting of an impeller and a matched vaned diffuser were designed and tested in a closed circuit centrifugal compressor test facility. The detailed measurements were carried out both at subsonic and supersonic Mach numbers at impeller outlet. The stage characteristics showed achievement of compressor stage total to total pressure ratio of 6.5 with an efficiency of 85%. The vaned diffuser shows good static pressure recovery of the order of around 0.6 with total pressure loss less than 2% at design point. Some of the salient experimental results are discussed in this paper.
