Industry/University Cooperative Research Activity: Hydrodynamics of Fluidization and Segregation

利用x射线和x射线密度计进行了多粒径流态化实验，并得到了一些分离的实验数据。本研究的目的之一是应用单尺寸流化流体动力学模型来预测大型流化床反应器中气泡的形状和大小；在高压下的反应堆中；在含管的流化床燃烧器中。第二个目标是完成三相流化流体动力学模型的开发，并将其应用于生物反应器。这些目标将通过在一台具有多个模型的超级计算机上进行计算，并将计算结果与文献数据和几个基本实验进行比较来实现。只要有可能，电脑制作的电影就会与实验电影进行比较。

A computer program was developed for multiparticle size fluidization, and some experimental data on segregation were also already obtained using x-ray and x-ray densitometers. One of the objectives of the study is to apply the single-size hydrodynamic model of fluidization to predict the shapes and sizes of bubbles in large-scale, fluid-bed reactors; in reactors under a high pressure; and in fluid-bed combustors containing tubes. A second objective is to complete the development of a hydrodynamic model for three-phase fluidization with an application to bioreactors. These objectives will be accomplished by making calculations on a supercomputer with several models by comparing the computations to literature data and to several fundamental experiments. Whenever possible, computer-generated movies will be compared to movies of experiments.
