| Abstract: | The advances and current state of the aerodynamic noise in turbomachinery are reviewed in terms of noise generation mechanism,numerical prediction and control method,respectively.Firstly,the theoretical development of noise generation mechanism is summarized in terms of discrete noise and broadband noise, in which the discrete noise consists of self noise and interaction noise,and the broadband noise comprises noises induced by flow distortion,blade tip clearance flow,viscous wake flow and vortex shedding.T... |
