摘要

温度或盐度变化导致的密度分层极大地影响了大气、海洋和湖泊中颗粒、液滴、气泡和小生物等物体的流动和沉积。根据分层、惯性（平流）和粘性（扩散）效应的相对大小，密度分层阻碍了垂直流动，并以各种方式显著影响孤立物体的沉降、一对物体之间的流体动力学相互作用以及悬浮物的集体行为。这篇综述讨论了海洋和大气中一些常见的流体-颗粒传输现象中的这些效应及其流体动力学机制。对这些机制的物理理解可以帮助我们更好地模拟这些现象，从而预测其地球物理、工程、生态和环境影响。《流体力学年度评论》第55卷预计最终在线出版日期为2023年1月。请参阅http://www.annualreviews.org/page/journal/pubdates用于修订估算。

Motion in Stratified Fluids

Density stratification due to temperature or salinity variations greatly influences the flow around and the sedimentation of objects such as particles, drops, bubbles, and small organisms in the atmosphere, oceans, and lakes. Density stratification hampers the vertical flow and substantially affects the sedimentation of an isolated object, the hydrodynamic interactions between a pair of objects, and the collective behavior of suspensions in various ways, depending on the relative magnitude of stratification, inertia (advection), and viscous (diffusion) effects. This review discusses these effects and their hydrodynamic mechanisms in some commonly observed fluid–particle transport phenomena in oceans and the atmosphere. Physical understanding of these mechanisms can help us better model these phenomena and, hence, predict their geophysical, engineering, ecological, and environmental implications. Expected final online publication date for the Annual Review of Fluid Mechanics, Volume 55 is January 2023. 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.
