摘要

高速分散多相流存在于许多环境和工程应用中，湍流、冲击波和颗粒之间存在复杂的相互作用。与不可压缩的两相流相比，可压缩两相流引入了新的运动尺度，这对模拟和实验提出了挑战。这篇综述的重点是跨越亚音速到超音速流动条件下的气体-粒子相互作用。概述了现有的马赫数相关阻力定律，其起源于18世纪的大炮发射，并从粒子分辨数值模拟中获得了新的见解。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含尘气体到稠密悬浮液的多粒子系统。《流体力学年度评论》第56卷预计最终在线出版日期为2024年1月。请参阅http://www.annualreviews.org/page/journal/pubdates用于修订估算。

Gas–Particle Dynamics in High-Speed Flows

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. Expected final online publication date for the Annual Review of Fluid Mechanics, Volume 56 is January 2024. Please see http://www.annualreviews.org/page/journal/pubdates for revised estimates.

期刊介绍： The Annual Review of Fluid Mechanics is a longstanding publication dating back to 1969 that explores noteworthy advancements in the field of fluid mechanics. Its comprehensive coverage includes various topics such as the historical and foundational aspects of fluid mechanics, non-newtonian fluids and rheology, both incompressible and compressible fluids, plasma flow, flow stability, multi-phase flows, heat and species transport, fluid flow control, combustion, turbulence, shock waves, and explosions. Recently, an important development has occurred for this journal. It has transitioned from a gated access model to an open access platform through Annual Reviews' innovative Subscribe to Open program. Consequently, all articles published in the current volume are now freely accessible to the public under a Creative Commons Attribution (CC BY) license. This new approach not only ensures broader dissemination of research in fluid mechanics but also fosters a more inclusive and collaborative scientific community.
