| 摘 要： | 本研究用风洞实验对矩形通道湍流边界层内嵌入的涡发生器参数进行了筛选；测量了单个涡发生器沿纵向对双侧壁面近壁边界层流场的干扰特性和通道嵌入涡偶的流动特性。找出了通道内嵌入涡发生器形成对近壁边界层流场干扰的较理想的涡发生器参数和漏偶的布局形式。

| Abstract: | An experimental investigation of vortex generators inlaidin turbulent boundary layer in a rectangular tunnel was made to selectthe ideal parameters. The disturbance behaviour of near wall boundarylayer flow field by a single vortex generator, and, the flow behaviour of vortex pairs inlaid in the tunnel were measured along longitudinal. The comparatiyely ideal parameters of vortex generators whichinlaid in the tunnel to affect on the flow field of near wall boundarylayer, and, the rather reasonable arrangement of vortex pairs areplesented in this paper. |
