Paper Abstract

Results are presented from an experiment designed to actively suppress a rotating stall condition in a low speed centrifugal compressor. The control system uses a circumferential array of twelve air injection jets located in the endwall of the compressor inlet. The system is able to suppress the eruption of a one-cell rotating stall condition in the compressor during stall initiation, but the eruption of high order stall conditions limits stable operating range extension. The controller is also capable of destabilizing the compressor and accelerating the eruption of the first spatial mode.
