Numerical investigation of the circumferential grooved casing treatment as well as analyzing the mechanism of improve stall margin

摘要：

The Circumferential Grooved Casing Treatment is known as a powerful method to en- hance the ow stability in compressors. Numerical investigation was conducted to study the in uence on a subsonic compressor performance with the circumferential grooved configuration. The calculated overall performance lines showed good agreement with the experiments. The fundamental ow mech- anism was obtained by detailed analyzing the ow-filed at the blade tip, which was the circumferential grooved casing treatment affects the compressor performance and ow field.
