摘　　要：阐述了动态冰浆流变性质的Bingham模型,并利用该模型计算了冰浆在层流和湍流状态下的摩擦因子,得到了冰浆在水平直管内流动的压降曲线,分别就层流和湍流情形分析了各种参数对流动压降的影响。In this paper, Bingham model is introduced to describe the theological behavior of dynamic ice slurry. The friction factors of laminar and turbulent flow are calculated by utilizing this model. Pressure drop curves of ice slurry flowing in a horizontal pipe are obtained. The parameters which affect the flow resistance under laminar and turbulent flow are analyzed.
