我们回顾了浓缩悬浮液流动成像的最新进展，重点是使用共聚焦显微镜在这些系统中获得单粒子水平的时间分辨信息。在激发了对悬浮流变性定量（共聚焦）成像的需求之后，我们简要地描述了进行这种实验所需的颗粒、样品环境、显微镜工具和分析算法。回顾的第二部分侧重于集中的“模型”硬球状悬浮液流动的微观方面，以及与非线性流变现象（如屈服、剪切局部化、壁滑移和剪切诱导有序）的关系。我们描述了布朗系统和非布朗系统，并展示了定量成像如何提高我们对微观动力学和体流之间联系的理解。
We review recent advances in imaging the flow of concentrated suspensions, focussing on the use of confocal microscopy to obtain time-resolved information on the single-particle level in these systems. After motivating the need for quantitative (confocal) imaging in suspension rheology, we briefly describe the particles, sample environments, microscopy tools and analysis algorithms needed to perform this kind of experiment. The second part of the review focusses on microscopic aspects of the flow of concentrated ‘model’ hard-sphere-like suspensions, and the relation to non-linear rheological phenomena such as yielding, shear localization, wall slip and shear-induced ordering. We describe both Brownian and non-Brownian systems and show how quantitative imaging can improve our understanding of the connection between microscopic dynamics and bulk flow.
