Abstract:

An experimental investigation, performed in a large scale low-speed, single-stage compressor, was conducted to provide the radial and chordwise distribution of basic unsteady pressure data on the stator. Radial and circumferential distributions of streamwise and transverse velocity fluctuations were determined at stations upstream, inside and immediately downstream of the stator. Analysis of the results indicated a correlation of the normalized transverse fluctuation velocity component with stator incidence angle. The fluctuations were very large in the endwall regions and were attributed to poor flow conditions generated in the hub and tip endwall regions of the rotor.
