摘要 采用数值模拟的方法,讨论和对比了平壁面、固定波形壁面和运动波形壁面上的双马赫反射中的激波结构和流场特点。计算结果表明,固定和运动波形壁面对气流的压缩效应使其在壁面处加速和减速时马赫杆发生明显的变形和卷曲。壁面的压缩在波后会产生曲面激波和脱体激波,使得上游流场中的激波相互作用更为复杂。与平壁面相比,固定波形壁上的压力和密度明显升高,而运动波形壁上的压力和密度随运动频率的增加而减弱。 In this paper,double Mach reflection over wavy and traveling-waves is investigated via numerical simulation.The characteristics of the shock structures and the field are presented.Results show that the compression and expansion induced by the curved walls induce obvious deformation of the Mach stem as the flow accelerates and decelerates near the wall.The curved and detached shock waves induced by the curved wall interact with the upstream flow,making the flow field much more complicated.Compared with the flows over flat wall,the density and pressure rise after shock are clearly increased,while those over moving walls decrease as the oscillation frequency increases.
