| 摘 要： | 本文利用剪切室研究了粘性颗粒剪切条件下的流动和分选情况,并针对实验现象和结果展开分析和讨论.实验结果表明,相比干颗粒而言,粘性颗粒相互黏结得更紧密,颗粒的流动性减弱,颗粒在流动过程中的浓度分布、应力状况以及分选均会受颗粒流动性减弱的影响.

| Abstract: | Compared with the dry particle systems,the flow and segregation of cohesive particle system will show different characteristics.This paper investigated the flow and segregation of cohesive particles in sheared flow,and carried out analysis and discussion on both the phenomenon and the results of experiments.Experimental results show that the cohesive particles cohere more closely and the mobility of particles turn weaker,and particle concentration distribution,stress and segregation will be impacted by the particle mobility. |
