High-speed disperse multiphase flows are present in numerous environmental and engineering applications with complex interactions between turbulence, shock waves, and particles. Compared with its incompressible counterpart, compressible two-phase flows introduce new scales of motion that challenge simulations and experiments. This review focuses on gas–particle interactions spanning subsonic to supersonic flow conditions. An overview of existing Mach-number-dependent drag laws is presented, with origins from eighteenth-century cannon firings and new insights from particle-resolved numerical simulations. The equations of motion and phenomenology for a single particle are first reviewed. Multiparticle systems spanning dusty gases to dense suspensions are then discussed from numerical and experimental perspectives.

高速流中的气体-粒子动力学


高速分散多相流存在于许多环境和工程应用中，湍流、激波和粒子之间存在复杂的相互作用。与不可压缩的同类流相比，可压缩两相流引入了新的运动尺度，对模拟和实验提出了挑战。本文重点介绍了从亚音速到超音速流动条件的气体-粒子相互作用。概述了现有的马赫数相关阻力定律，起源于 18 世纪的大炮射击和来自粒子分辨数值模拟的新见解。首先回顾了单个粒子的运动方程和现象学。然后从数值和实验的角度讨论了从多尘气体到致密悬浮液的多粒子系统。
