Resolving the mechanics of wall-mounted finite airfoil noise production

来自航空运输和风力涡轮机的噪音是环境噪音污染中一个迅速增长的组成部分，必须减少以改善公众健康和福祉。潜艇还必须具有低声学特征以确保其隐身性。在这些技术中产生噪音的共同来源是翼型，但我们不了解他们如何在真实的，复杂的环境中产生噪音。该项目旨在了解流体流动如何与壁挂式有限翼型相互作用以产生声音。该项目旨在通过一种新颖的风洞实验和数值研究来确定噪声产生的物理特性。这种增强的理解将创造更好的翼型噪声预测和控制策略，在未来。

Noise from air transportation and wind turbines is a rapidly growing component of environmental noise pollution that must be reduced to improve public health and well-being. A submarine must also have a low acoustic signature to ensure its stealthiness. The common source of noise generation among these technologies is the airfoil, yet we do not understand how they create noise in real, complex environments. This project aims to understand how fluid flow interacts with a wall-mounted finite airfoil to produce sound. The project aims to identify the noise producing physics via a novel wind tunnel experiment and numerical study. This enhanced understanding will create better airfoil noise prediction and control strategies in the future.
