单颗粒在浓相悬浮体中的沉降运动

SETTLING OF SINGLE PARTICLE IN DENSE SUSPENSION

用磁感测量法对颗粒在浓相悬浮体中的沉降过程进行实验研究。

The settling process of single particles in dense suspension was experimentally investigated by using magnltic particle tracer and magnetic susceptometer. The relationship of superficial viscosity, μs, of dense suspensions versus the solid concentration, ε, of the dense suspension was obtained as follows:and the diagram of the relationship of Ars. vs. Lys was also presented.
