In this review article, we focus on collective motion in externally driven colloidal suspensions, as well as how these collective effects can be harnessed for use in microfluidic applications. We highlight the leading role of hydrodynamic interactions in the self-assembly, emergent behavior, transport, and mixing properties of colloidal suspensions. A special emphasis is given to recent numerical methods to simulate driven colloidal suspensions at large scales. In combination with experiments, they help us to understand emergent dynamics and to identify control parameters for both individual and collective motion in colloidal suspensions

利用外部驱动的胶体悬浮液的集体效应：实验和模拟

在这篇评论文章中，我们重点关注外部驱动的胶体悬浮液中的集体运动，以及如何利用这些集体效应来用于微流体应用。我们着重指出了水动力相互作用在胶体悬浮液的自组装，涌现行为，运输和混合特性中的主导作用。特别强调了最近的数值方法，以大规模模拟驱动的胶体悬浮液。结合实验，它们可以帮助我们了解紧急动态，并确定胶体悬浮液中个体运动和集体运动的控制参数
