摘要

为抑制叶片表面流动分离，提升叶片气动性能，提出在叶片表面安装涡流发生器的设计方案。以DU97-W-300叶片段设置涡流发生器为研究对象，采用正交实验设计方法，探究该叶片段涡流发生器高度、长度、安装角、弦向安装位置、间距、节距对叶片气动性能的影响，从而确定涡流发生器参数设计基本规律。研究结果表明：影响叶片气动性能大小的涡流发生器参数依次为涡流发生器间距、节距、长度、高度、弦向安装位置、安装角；最优涡流发生器参数组合规律为高度0.75ξ（ξ为叶片边界层厚度）、长度1.60ξ、安装角20.0°、弦向安装位置10%叶片弦长、间距1.60ξ、节距0.80ξ，可以使该叶片最大升力系数增大40%，最大失速攻角增大9.5°。

Abstract

In order to inhibit the flow separation on blade surface and improve the aerodynamic performance of the blade

the design scheme of installing vortex generator on the blade surface is proposed. Taking DU97-W-300blade section with vortex generator as the research object

the orthogonal experimental design method is used to investigate the influences of height

length

installation angle

chord installation position

spacing and pitch of the vortex generator on the aerodynamic performance of the blade section

so as to determine the basic law of vortex generator parameter design. The results show that

the vortex generator parameters that affect the magnitude of aerodynamic performance of the blade are as follows: spacing

pitch

length

height

chord installation position

and installation angle of the vortex generator. The optimal vortex generator parameter combination law is: height of 0.75ξ(ξ is blade boundary layer thickness)

length of 1.6ξ

installation angle of 20°

chord installation position is 10% blade chord length

spacing of 1.6ξ

pitch of 0.8ξ

which can increase the maximum lift coefficient of this blade by 40% and the maximum stall angle of attack by 9.5°.
