摘要
本文提出了细颗粒悬液粘度的计算模型,经黄河中下游十余个悬沙级配的试验验证,及与国内多家对悬液粘度试验结果的比较,表明本计算模型有较好的适应性.文中还列举了一些应用本模型计算不同条件下含沙水流的粘度及有关的水流泥沙运动参数的例子.
A model for calculating viscosity of suspension with fine particles is presented in this paper. It was verified by a lot of Theological experiments for more than ten groups of particle-size distribution,sampling from the Middle ,and Lower Yellow River. A comparison of experimental results, obtained by different researchers also was made.The expression of reduced viscosity η and yield stress τB for suspension in forms of eq. 2 and eq. 3 seem to be successful in the estimation of rheological parameter of sediment-ladden flow.Some examples for calculating parameters of sediment flow motion by using this model are illustraed in the paper.
