| 摘 要： | 本文介绍了一种新型的凹型面埋入式涡流发生器的工作机理。并介绍在一个小宽高比二元单边凹壁亚声扩压壁前段出现气流分离,角落区域有倒流的情况下,采用适当几何参数的该型式涡流发生器大大减小分离区的范围,从而提高了扩压器静压恢复系数和减小总压损失系数的试验结果。

| Abstract: | The paper presents the principle of boundary layer control for submerged vortex generators of concave shape. The test study of separation control by the submerged vortex generators in a low aspect ratio subsonic diffuser with divergent concave-shaped surface is introduced . The experimental results show that the flow separation range in the diffuser is reduced enormously, the static pressure recovery coefficient is increased and the total pressure loss is also decreased for the proposed diffuser, if the proper geometrical parameters of the submerged vortex generator are selected. |
