Abstract: Flow-induced acoustic resonance, a complex coupling phenomenon between the flow and sound fields, can cause high-intense tone noise over 160 dB, which can not only severely discomfort the cabins, but also lead to acoustic fatigue issues to the nearby structures. This problem has attracted the attention of more and more designers for a variety of engineering applications, such as rocket combustors, weapon bay for military applications, sunroof of cars, and tube bank of heat exchangers. Meanwhile, enough cases have suggested that acoustic resonance can also be detected in aeroengine compressors as a potential reason for the failure of aeroengine compressor blades, making it a growing research hotspot. However, the underlying mechanism of acoustic resonance is still an open issue. A comprehensive review on the present research in theoretical and experimental studies, predict and control methods of acoustic resonance is summarized to deepen the basic understanding of flow-induced blade failures, as well as to improve the design and troubleshooting abilities of aeroengine compressors.

Key words: compressor, blade failure, flow-induced vibration, acoustic resonance, vortex sound interaction
