Abstract

© 2018 by the American Institute of Aeronautics and Astronautics, Inc. All rights reserved. Under a transformation to streamline coordinates, it is possible to generalise Rapid Distortion Theory results, applied to sheared flow, to include a developing flow. This allows inclusion of large geometrical effects, for example a thick aerofoil, to high-frequency acoustic disturbances. These ideas are developed by considering a shear flow passing over a protrusion from a wall, and extended to include the effect of a trailing-edge.
慢变剪切流中的尾缘噪声
©2018由美国航空航天研究所,Inc。版权所有。在对流线坐标的转换下,有可能将应用于剪切流的快速畸变理论结果推广到包括发展流。这允许包含大的几何效应,例如一个厚的翼型,高频声干扰。这些想法是通过考虑从墙的突出部分通过的剪切流而发展起来的,并扩展到包括尾缘的影响。
