摘　　要：本文面向初学者介绍气动声学和流动噪声研究的过去和现况,以声比拟为主要线索展开讨论,澄清了一些常见概念和误区,并解释了代表性问题的气动发声机制,兼顾评述了计算方法和实验技术,最后展望了未来可能有所发展的研究方向。In this review paper,we give a brief introduction of the past and present of the research in aeroacoustics and flow-induced noise.The main attention is focused on acoustic analogy,from which the main mechanisms of noise generated aerodynamically for representative set-ups can be explained.We also briefly introduce the related computational schemes and testing methods.Overall,we hope this paper will help to clarify some misconceptions in aeroacoustics,especially those from beginners.Finally,we propose some possible important research directions for the future.
