Abstract
通过在叶栅上游放置圆柱产生各向异性的湍流尾迹,并与下游叶片相互干涉产生干涉噪声,研究了仿生学锯齿尾缘构型对圆柱-叶栅干涉噪声的影响.针对西北工业大学航空叶轮机气动力学与气动声学实验室(TAAL)低压涡轮平面叶栅,在不同来流速度的情况下,使用远场圆弧阵列测量了叶栅远场噪声,并基于CLEAN-SC数据处理算法使用由31个传声器组成的线阵列测量识别了不同叶栅的尾缘噪声,得到了圆柱尾迹来流下锯齿尾缘构型的降噪效果.实验结果表明,不同锯齿尾缘构型的降噪效果存在差异,当来流为圆柱尾迹时,对叶栅尾缘噪声的识别测量结果显示此时锯齿尾缘降噪效果有限,最佳降噪量仅为1.296dB,当来流速度较高时,采用的锯齿尾缘构型无法降低圆柱-叶栅干涉尾缘噪声.
