Abstract : The application of laser anemometry techniques in turbomachinery facilities is a challenge dilemma requiring an anemometer system with special qualities. In this work we describe the use of a novel laser anemometry technique applied to a small 4.5 kg/s, 4:1 pressure ratio centrifugal compressor. Sample velocity profiles across the blade pitch are presented for a single location along the rotor. The results of the intra-blade passage velocity measurements will ultimately be used to verify CFD 3-D viscous predictions.
