Dynamics of Suspensions Subject to Transient Flows

受流动影响的悬浮液的宏观特性通常取决于组成悬浮液的各个组成颗粒的运动及其旋转和随后的取向。因此，对悬浮液流动行为的任何基本理解都应该考虑微观水平上的系统动力学。此外，应该研究瞬变流动以及在很大程度上主导过去研究工作的稳态流动。在这项研究工作中，将采用新的光学方法来测量胶体大小的颗粒在瞬变流动过程中的运动。

The macroscopic characteristics of a suspension subjected to flow are generally dependent upon the motions of the individual constituent particles making up the suspension and their rotations and subsequent orientation. Any fundamental understanding of the flow behavior of a suspension should, therefore, consider the dynamics of the system at the microscopic level. Additionally, transient flows should be studied as well as the steady state flows which have largely dominated past research efforts. New optical methods which allow the motions of colloidal-sized particles to be measured during transient flows will be employed in this research effort.
