摘要
在前人的理论和研究成果的基础之上,利用动量守恒所建立的清水速度、固体颗粒速度和浆体流速之间的关系,通过分析水平管道中推移质与悬移质组成的几何关系,对于水平管道中推移质与悬移质的之间比例与平均流速之间的关系进行了深入的研究,得出推移质与悬移质与平均流速之间的关系式,确定了管道输送中的重要系数K4和浮游界限速度vB,通过实验资料验证符合良好。
In this paper, on the basis of forefathers＇ research and theory, relations among velocity of water ,that of solid particles and that of settling slurry have been established by the momentum transmission. Through analysis of the geometry relation of salutations particles and suspension particles in the horizontal pipe, deep research is carried out on the relation of the proportion of salutations particles and suspension particles and mean velocity of flow in the horizontal pipe. The important coefficient K4 and velocity for heterogeneous flow VB are established, which agrees with the experimental data well.
