Kinetics of Aggregation in Magnetic Suspensions

丹尼斯·维尔茨 这项工作的目的是研究与磁流变液相关的各种问题。 这种流体类似于更广泛研究的电流变流体，当电场被施加时，电流变流体的粘性发生急剧变化。 应用。 已经提出了这种材料的许多应用，例如离合器和减震器。 本工作的主要目的是研究微结构的演变时，施加磁场，也当同时施加磁场和剪切场。 视频显微镜和小角度光散射将用于探测微观结构。

ABSTRACT Denis Wirtz This work is aimed at studying a variety of issues associated with magneto-rheological fluids. Such fluids are analogous to the more widely studied electro-rheological fluids which undergo dramatic changes in their viscous properties when and electric field is applied. Many applications have been proposed for such materials, such as clutches and shock absorbers. The principal aim of this work is to study the microstructure evolution when magnetic field is applied and also when both a magnetic and a shear field is applied. Video microscopy and small angle light scattering will be used to probe the microstructure.
