摘要

化学梯度，即化学浓度和成分的空间变化，在从生物和环境系统到工业过程的各种环境中无处不在。这些热动力通常在驱动此类系统中发生的传输过程中发挥着核心作用。本综述将重点讨论由化学梯度驱动的相变迁移现象--扩散oresis。首先，我们将重温支配这种传输的基本物理化学流体力学。然后，我们讨论了在自然和人工环境中的流动系统中出现的扩散现象。通过探讨遇到和利用化学梯度的各种情况，我们旨在证明扩散流的重要性及其在技术应用中的最新发展。

Physicochemical Hydrodynamics of Particle Diffusiophoresis Driven by Chemical Gradients

Chemical gradients, the spatial variations in chemical concentrations and components, are omnipresent in environments ranging from biological and environmental systems to industrial processes. These thermodynamic forces often play a central role in driving transport processes taking place in such systems. This review focuses on diffusiophoresis, a phoretic transport phenomenon driven by chemical gradients. We begin by revisiting the fundamental physicochemical hydrodynamics governing the transport. Then we discuss diffusiophoresis arising in flow systems found in natural and artificial settings. By exploring various scenarios where chemical gradients are encountered and exploited, we aim to demonstrate the significance of diffusiophoresis and its state-of-the-art development in technological applications.

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.
