Abstract

This paper presents results of computational and experimental studies of the evolution of turbulent mixing in three-layer gas systems with the development of hydrodynamic instabilities, in particular, the Richtmyer–Meshkov and Kelvin–Helmholtz instabilities, under the action of shock waves. One of the contact boundaries between gases is flat, while the other one has the form of a chevron. The numerical simulations are carried out both with and without initial perturbations of contact boundaries. It is shown that the roughness of the contact boundary significantly affects the width of the mixing zone.

使用 NUT3D、BIC3D、EGAK 和 MIMOSA 数值代码对带有雪佛龙接触边界的气体系统中的湍流混合进行数学建模

摘要本文介绍了在冲击波作用下，三层气体系统中湍流混合演变的计算和实验研究结果，以及流体力学不稳定性的发展，特别是里氏-梅什科夫不稳定性和开尔文-赫姆霍兹不稳定性。气体之间的一个接触边界是平的，而另一个接触边界则是楔形的。在接触边界有初始扰动和无初始扰动的情况下都进行了数值模拟。结果表明，接触边界的粗糙度会显著影响混合区的宽度。
