Single-Stage Evaluation of Highly-Loaded High-Mach-Number Compressor Stages 5. Data and Performance of Baseline, Corner-Blow Wall Suction and Combined Corner Blow Wall Suction Stator
A single-stage compressor with a rotor tip speed of 1600 ft/sec and a 0.5 hub tip ratio was used to investigate the effects of several stator endwall treatment methods on stage range and performance. These endwall treatment methods consisted of stator corner-blow, annular wall suction upstream of stator leading edge, and combined corner-blow and annular wall suction. The overall stage performance with corner blow was essentially the same as the baseline performance. The performance for the annular wall suction and the combined corner-blow and wall suction showed a reduction in peak efficiency of 2.5 percentage points compared to the baseline data. (Author)
