摘要

现有的管道式风机噪声控制方法通常需要修改风机或流道结构,并且安装消声器可能会影响通风效率。为了解决上述方法的不足,我们提出将声学超材料应用于管道风机噪声控制。设计了一种亥姆霍兹型声学超材料,可以同时控制前四阶音调噪声,这种超材料的特点是体积小,外形薄,可以灵活地应用于风扇管道。利用理论模型和实验验证分析了这种超材料作为管道旁路时的吸声特性。研究结果表明,作为管道旁路时,声学超材料在吸收频率处表现出显著的声传输损失。为了综合评价声学超材料对管道风机的影响,采用计算流体力学(CFD)与声学有限元(FEM)相结合的混合仿真方法。数值模拟结果表明,声学超材料可以有效地衰减管道风扇噪声,同时保持对通风效率的最小影响。

Design and evaluation of an acoustic metamaterial for ducted fan noise control
Existing noise control methods for ducted fans usually require modifications to the fan or runner structure, and the installation of silencers may affect ventilation efficiency. In order to address the shortcomings of the above methods, we propose the application of acoustic metamaterials to ducted fan noise control. A Helmholtz-type acoustic metamaterial has been designed to simultaneously control the first four orders of tonal noise, and this metamaterial is characterized by its small size and thin profile, allowing it to be flexibly applied to fan ducts. The acoustic absorption characteristics of this metamaterial, when employed as a duct bypass, have been analyzed using theoretical models and experimental validation. The findings indicate that the acoustic metamaterial exhibit significant acoustic transmission loss at the absorption frequency when employed as a duct bypass. To comprehensively evaluates the effects of acoustic metamaterials on ducted fans, a hybrid simulation approach combining Computational Fluid Dynamics (CFD) with the acoustic Finite Element Method (FEM) is utilized. The numerical simulation results indicate that acoustic metamaterials can effectively attenuate ducted fan noise while maintaining a minimal impact on ventilation efficiency.

期刊介绍: Since its launch in 1968, Applied Acoustics has been publishing high quality research papers providing state-of-the-art coverage of research findings for engineers and scientists involved in applications of acoustics in the widest sense. Applied Acoustics looks not only at recent developments in the understanding of acoustics but also at ways of exploiting that understanding. The Journal aims to encourage the exchange of practical experience through publication and in so doing creates a fund of technological information that can be used for solving related problems. The presentation of information in graphical or tabular form is especially encouraged. If a report of a mathematical development is a necessary part of a paper it is important to ensure that it is there only as an integral part of a practical solution to a problem and is supported by data. Applied Acoustics encourages the exchange of practical experience in the following ways: • Complete Papers • Short Technical Notes • Review Articles; and thereby provides a wealth of technological information that can be used to solve related problems. Manuscripts that address all fields of applications of acoustics ranging from medicine and NDT to the environment and buildings are welcome.
