| Abstract | An extensive experimental study of the flow in centrifugal impellers, using a low speed centrifugal compressor rig, has been carried out in the Engine Laboratory, and is reported in References 1 to 4. The major conclusions drawn from this test programme were that flow detachment from the blade surfaces constitutes one of the major causes of poor distribution and flow instability, and that slotted blades offered the most promising means of delaying flow detachment. The optimum slot configuration was determined experimentally, and the behaviour of slotted and unslotted blades was compared on the low speed rig.
The present memorandum describes an experiment conducted on a high speed centrifugal compressor rig to compare the performance of uncambered aerofoil blades with and without slots. |
