Understanding and predicting airfoil noise in real-world turbulence

该项目旨在了解和预测湍流与翼型相互作用产生的噪音，以推进航空发动机、风力涡轮机、船舶、冷却风扇和无人机的设计。提出了一种新型的消声风洞实验，将复杂湍流流场与翼型相互作用以及产生噪声的物理特性联系起来。该项目的预期成果是新的半解析噪声预测模型和可用于实际噪声控制的科学知识。预期的好处包括安静的航空航天、海军和可再生能源技术，减少环境噪音污染和提高生活质量。

This project aims to understand and predict the noise produced by turbulence interacting with an airfoil to advance the design of aeroengines, wind turbines, marine vessels, cooling fans and drones. A novel anechoic wind tunnel experiment is proposed to link complex turbulent in-flow with the behaviour of the flow as it interacts with the airfoil and the noise-producing physics. The intended outcomes of this project are new semi-analytical noise prediction models and scientific knowledge that can be harnessed for practical noise control. Anticipated benefits include quiet aerospace, naval and renewable energy technologies, reduced environmental noise pollution and better quality of life.
