摘要

报告详细介绍了UTIAS的混合消声风洞，重点介绍了其设计和性能特点。研究结果表明，该风洞可以实现均匀的气流和极低的湍流强度，与类似的开环风洞设施性能相当。消声室有效降低了噪声，其截止频率约为 160 Hz，为广泛的航空声学测量提供了合适的环境。风洞在各种空气动力学和航空声学研究中的应用说明了风洞的多功能性，展示了 NACA 0012 机翼、多元素 30P30N 配置和有限跨度机翼研究等实例。此外，该设施的总体声压级（OASPL）与全球其他著名的航空声学风洞相当，表明其在该领域具有竞争力的性能和实用性。

Design and characterization of the university of Toronto hybrid anechoic wind tunnel

A detailed overview of the hybrid anechoic wind tunnel at UTIAS is presented, highlighting its design and performance features. The findings demonstrated that the tunnel achieves a uniform flow with very low turbulence intensity, matching the performance of similar open-loop wind tunnel facilities. The anechoic chamber effectively reduces noise with a cutoff frequency of around 160 Hz, providing a suitable environment for a broad spectrum of aeroacoustic measurements. The versatility of the wind tunnel was illustrated through its application in various aerodynamic and aeroacoustic studies, showcasing examples such as the NACA 0012 airfoil, the multi-element 30P30N configuration, and finite-span airfoil investigations. Moreover, the facility's Overall Sound Pressure Level (OASPL) is on par with other prominent global aeroacoustic wind tunnels, indicating its competitive performance and utility in the field.

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.
