摘要
利用RV20-M型转子粘度仪测定了玻璃珠-甘油体系的表观粘度,提出了体系表观粘度的关联式。并对单颗粒-流体系统的Re数和粒子的曳力系数进行修正,给出了一个适用于Re_m<2×10~5的多颗粒-液体系统中粒子曳力系数的关系式。
The apparent viscosity of glycerin-glass beads systems was measured by use of a RV20-M type viscometer. A correlation of the apparent viscosity was proposed. The correlation used to predict the drag coefficient of multiparticle-fluid systems, which is applicable for Re number Re_m<2×10~5, was given after some modifications were made for the Re number and the drag coefficient of single particle—fluid systems.
