摘要
从清水与固体颗粒之间的动量传递入手,分析了水平管道内沉降性浆体流动时清水与固体颗粒之间的相互作用机理,分别得到了输送流体、固体颗粒和浆体的速度分布。同时,根据固体颗粒的起动条件,研究在不同水力坡度下的堆积层厚度的变化规律。用此方法所得计算结果与试验数据吻合较好。
Following a basic study of the momentum transfer between the freshwater and solid particles, an analysis is made of the mechanism of interaction between the freshwater and solid particles in a horizontal pipeline in conveyance of a slurry containing settiement-prone particles. Through analysis, the distributions of velocities of fluid, solid particles and slurry are well defined. Given the moving conditions of solid particles, the law governing the variation of the thickness of the layer of deposited particles under different hydraulic gradients is brought to light. The results obtained using the models are in good agreement with the experimental data.
