Fluidization Mechanisms in Slurry Flows

点击翻译按钮获取中文摘要

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.
