A Numerical Research into the Impact of Air System Bleeding on the Compressor Performance

摘要：

Bleed air from the high pressure compressor has taken up 3-5％ in the air system. However, there are not many studies on the compressor performance after bleeding. By analyzing the low-speed single-stage compressors, this paper presents six different bleeding plans according to their influence mechanism on the compressor performance. A numerical simulation is conducted to study the influence of bleeding on the compressor total pressure rise and stability margin. The results showed that for the stators with large flow separation in the corner, it is better to bleed air both from the suction surface of the casing and the blade suction surface near the hub at the same time, so as to improve total pressure rise and stability margin with a small amount of bleed air. The conclusion steadily supports a concept that it is very necessary to combine the air system bleeding with the compressor flow control during engine performance study.
