激波和湍流相互作用的数值模拟

摘要

We provide an overview of recent progresses in numerical simulations of the shock wave/turbulence interactions, including the interactions of shock wave with homogeneous and isotropic turbulence, turbulent boundary layers, turbulent jets and wakes. The characteristics of the interaction depend on a variety of factors, such as the strength, location and shape of the shock wave, the boundary conditions, as well as the state of turbulence and the compressibility of the incoming flow. The interaction substantially results in considerable changes in the flow structures, the features of shock wave and the turbulent statistical properties. Finally, we discuss some issues in the numerical simulation of shock wave/turbulence interactions.%本文综述了关于激波和湍流相互作用数值模拟的近期研究进展,主要包括激波和均匀各向同性湍流、激波和湍流边界层、激波和射流以及激波和尾迹的相互作用.激波和湍流相互作用特性受到诸多因素的影响,如激波的强度、位置、形状和流动边界以及来流的湍流状态和可压缩性等.激波和湍流的相互作用会引起流场结构、激波特性和湍流统计特性的显著变化.最后简要讨论了激波和湍流相互作用数值研究需要关注的一些问题.
