Study on the Acoustic Resonance Mechanism in a Compressor Cavity Based on a Flat Cascade Model

Abstract

AbstractIn response to the research challenges concerning the mechanism of acoustic resonance excitation in aero-engine compressors, internal noise testing experiments were conducted on a high-pressure compressor. The experiments demonstrated that when ...Practical ApplicationsAcoustic resonance in compressors represents a highly coupled fluid–acoustic-structure multiphysics phenomenon that severely compromises structural integrity and may lead to blade fatigue failure. From a physical perspective, ...
