A comprehensive review on the mechanism of flow-induced noise and related prediction methods
摘要
Abstract
In this paper, a comprehensive review is presented on the mechanism of flow-induced noise and the related prediction methods. The review consists of four aspects: noise of submerged jets, Turbulent Boundary Layer(TBL)noise, rotor noise, and flow over cavities. The mechanism and applicability of noise prediction in the field of engineering using Lighthill acoustic analogy, Kirchhoff formulation, and the theory of vortex sound are explained in detail. Furthermore, numerical simulation methods of flow-induced noise are summarized. Specifically, Lighthill acoustic analogy presumes the noise source to be known in advance, which simplifies its engineering practice; nevertheless, it is defective to describe the exact interaction be⁃tween flow and sound. Meanwhile, any sound field could be calculated through Kirchhoff approach without source details, but the calculation in the near-field region directly affects the overall precision of the noise field. Finally, profound research on the interaction between vortex and potential flow indicates that the theo⁃ry is promising when it comes to the production and transformation of acoustic energy. In this case, free field flow noise is presented in quadruple form, while it is presented in dipole form when hard wall bound⁃ary exists including operating screws, which serves as a much more effective sound source.关键词
