  • 摘要: 实验发现,一定条件下超声速后掠圆柱的前半圆上可能发生定常涡引起的转捩.为了模拟高空超音速飞行器后掠翼前缘,以无限展向长度后掠椭圆柱为模型,基于eN方法,根据积分的N值,分析了迎风轴长度、Reynolds(雷诺)数、后掠角和Mach(马赫)数等参数的变化对超音速后掠椭圆柱横流定常涡不稳定性的影响.研究结果表明,后掠椭圆柱的迎风轴长度增加,会使横流定常涡的不稳定性增强;Reynolds数增大,使横流定常涡模态的不稳定性增强;不稳定性的强度与Reynolds数的大小为近似线性关系;飞行高度增加,Mach数变大,使横流定常涡的不稳定性变弱;后掠角在一定范围内的变化对横流定常涡的不稳定性影响不大.这些结果有助于提高对高空超音速飞行器翼前缘转捩机理的认识,为横流转捩预测提供理论指导
