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.

编制了多粒径流态化计算程序， 并获得了一些有关偏析的实验数据 使用X射线和X射线密度计。 的目标之一 研究的目的是将流化的单尺度流体力学模型应用于 预测大规模流化床中气泡的形状和大小 反应器;在高压下的反应器中;以及在流化床中 含有管子的燃烧室。 第二个目标是完成 三相流态化流体力学模型的建立 在生物反应器中的应用。 这些目标将得以实现 通过在一台超级计算机上用几种模型进行计算， 将计算结果与文献数据和几个 基本实验。 只要有可能，电脑制作的电影 将被比作实验电影。
