中文摘要：

本文利用正交实验方法,以边界层不可压形状因子作为主要实验指标,通过数值模拟对一非对称斜坡型微型涡流发生器的结构参数进行了优化,对各结构参数进行极差分析后的结果表明,涡流发生器的高度对不可压形状因子和边界层厚度的影响最大,其次是其宽度,长度的影响作用最小。同时给出一系列较优的比例参数,使涡流发生器可以达到对激波边界层干涉较优的控制效果,其适应工况在来流Ma=2.3～2.8之间。这对涡流发生器的初期设计具有一定指导意义。

英文摘要：

Based on the orthogonal test design and numerical simulation, the structural parameters of an asymmetric ramp micro-vortex generator are optimized by using incompressible shape factor as the main test index. The results of range analysis showed that the vortex generator＇s height has the greatest impact on the incompressible shape factor and the boundary layer thickness, followed by the influence of its width, length. A series of optimal scale parameter are represented in this paper, which can make the micro-vortex generator improve the health of the boundary layer and be suitable for the working condition at Mach number ranging from 2.3 to 2.8. The results have guiding significance for the initial design of micro-vortex generators.
