Abstract:为改善二元超声速进气道前体激波与侧壁面边界层干扰问题,提出了一种在侧壁开泄流气缝的流场控制方法并进行了数值仿真验证,然后研究了侧壁面开缝的宽度、位置、角度等典型几何参数对进气道性能的影响规律。结果表明:设计马赫数下侧壁开缝使进气道唇口角区处的溢流明显减小,进气道内通道进口流场得到改善,进气道流量系数提高2.27%、喉道截面总压恢复系数提高3.37%;在非设计状态下,进气道性能也有一定的改善。典型几何参数研究结果表明,当侧壁开缝位置位于前体斜激波位置(L=-1.4~-0.21)、开缝宽度为0.85~1.10倍当地边界层厚度时,对进气道性能的改善效果最佳,而开缝的角度影响并不明显。
