在马赫数为1.23和1.41的激波作用下，进行了空气/SF6倾斜界面不稳定性的激波管实验。采用并行算法和多粘性流体和湍流大涡模拟（LES）程序（MVFT）进行数值模拟。模拟再现了激波加速界面的发展过程。复杂的波结构，例如，激波的传播、折射和反射在流动中清楚地显示出来。模拟得到的界面演化图像与实验结果一致。湍流混合区的宽度以及气泡和尖峰的位移也与实验数据吻合较好。验证了MVFT模拟界面失稳问题的可靠性和有效性。当激波马赫数较大时，注入TMZ的能量越多。因此，扰动界面发展得更快。
The shock tube experiments of inclined air/SF6 interface instability under the shock wave with the Mach numbers 1.23 and 1.41 are conducted. The numerical simulation is done with the parallel algorithm and the multi-viscous-fluid and turbulence (MVFT) code of the large-eddy simulation (LES). The developing process of the interface accelerated by the shock wave is reproduced by the simulations. The complex wave structures, e.g., the propagation, refraction, and reflection of the shock wave, are clearly revealed in the flows. The simulated evolving images of the interface are consistent with the experimental ones. The simulated width of the turbulent mixing zone (TMZ) and the displacements of the bubble and the spike also agree well with the experimental data. Also, the reliability and effectiveness of the MVFT in simulating the problem of interface instability are validated. The more energies are injected into the TMZ when the shock wave has a larger Mach number. Therefore, the perturbed interface develops faster.
