Fluidization Mechanisms in Slurry Flows

本实验研究旨在确定两种机制的相对重要性，这两种机制负责固体颗粒在流动液体中的悬浮。一个是流体-粒子相互作用，另一个是粒子-粒子相互作用。测量颗粒浓度，压力，流体以及颗粒速度将获得通过一个均匀尺寸的通道悬浮液的水平流动。这些量在海峡上的横向分布将被用来推断两种悬浮机制的局部重要性。研究结果对浆液输送管道和堵塞现象具有重要意义。

This experimental investigation is designed to establish the relative importance of two mechanisms which are responsible for the suspension of solid particles in a flowing liquid. One is fluid-particle interactions, and the other is particle- particle interactions. Measurements of particle concentration, pressure, and fluid as well as particle velocities will be obtained for the horizontal flow of suspensions through a uniform size channel. The lateral distribution of these quantities across the channel will be used to infer the local importance of the two suspension mechanisms. The results have an important bearing on slurry transport pipelines and plugging phenomena.
