| 摘 要： | 风扇噪声是风洞中最主要的噪声源.高噪声不仅会对风洞中的实验结果不利,影响实验结果的可靠性和精确性,而且还会带来严重的噪声污染.因此,对风洞风扇桨叶进行低噪声设计研究具有十分重要的意义.主要研究了风洞风扇桨叶的低噪声设计,采用工程估算法与试验结合的方法对风洞风扇噪声情况进行分析.以某翼型桨叶为研究对象,通过修改叶型尾缘厚度对风洞风扇进行了低噪声优化设计.

| Abstract: | Fan noise is the most primary noise resource in the wind tunnel.High-noise not only affects the dependability and the experiment accuracy of the wind tunnel,but also brings serious noise pollution.Consequently,to design low-noise vanes of wind tunnel fan is of great significant.This paper is aimed at studying the approach to design low-noise vanes of wind tunnel fan,using the approach of engineering calculation and experiment to analyze the noise levels of wind tunnel fan.To take the vane as object,optimized design of low-noise is researched by revising the air foil parameters.It studies the effects of cauda edge thickness on the aerodynamic performance of wind tunnel fan and noise levels,and an effective approach of low-yawp vanes design was found. |
