摘要

在本研究中，研究了带有穿孔筛网和部分吸声内衬的同轴管的声波分析。所考虑的几何形状包括一个无限长管道，该管道位于半无限长圆柱形管道中，使得外管道的内表面覆盖有部分吸声内衬。由于存在局部衬砌问题，采用Jones方法和模式匹配方法求解。给出了穿孔筛网和局部衬砌等问题参数对辐射现象的影响。

Acoustic wave radiation from a coaxial pipe with partial lining and inner perforated screen

In this study, the analysis of sound waves from a coaxial pipe with a perforated screen and a partial acoustic absorbing lining is investigated. The geometry under consideration consists of an infinite pipe placed in a semi-infinite cylindrical pipe such that the inner surface of the outer pipe is covered with a partial acoustic absorbing lining. Because of the partial lining, the solution is obtained with both the Jones’ method and the Mode-Matching method. The effects of the problem parameters such as perforated screen and partial lining on the radiation phenomenon are presented.

期刊介绍： International Journal of Aeroacoustics is a peer-reviewed journal publishing developments in all areas of fundamental and applied aeroacoustics. Fundamental topics include advances in understanding aeroacoustics phenomena; applied topics include all aspects of civil and military aircraft, automobile and high speed train aeroacoustics, and the impact of acoustics on structures. As well as original contributions, state of the art reviews and surveys will be published. Subtopics include, among others, jet mixing noise; screech tones; broadband shock associated noise and methods for suppression; the near-ground acoustic environment of Short Take-Off and Vertical Landing (STOVL) aircraft; weapons bay aeroacoustics, cavity acoustics, closed-loop feedback control of aeroacoustic phenomena; computational aeroacoustics including high fidelity numerical simulations, and analytical acoustics.
