Abstract / Description of output
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.
