摘要： 考察了气-液鼓泡塔中气泡流和液流的运动规律，提出了将分散的气泡流连续介质化的假设和基于容积通量的流体力学表达方式，建立了气含率分布与液体内循环流动结构的连续介质流模型，较好地揭示了液体循环流动规律. 模型计算与实验结果吻合.

关键词: 鼓泡塔, 气泡流, 气含率, 内循环流动

Abstract: Gas–liquid flow in bubble columns is studied by taking dispersed bubbles and liquid as co-existing continua. The mathematical models of gas hold-up distribution and the liquid circulation are developed under the assumptions that the gas phase is non-Newtonian and there is no frictional force between gas and liquid phases. The calculated results are coincident with experimental data satisfactorily.

Key words: circulating fluidized bed, solids holdup fluctuation, prediction, phase space reconstruction
