摘要
本文从颗粒流态出发,探讨颗粒不同流态特征及其转化机制,并分析了颗粒流动过程中的应力本构关系,总结了非均匀颗粒流动特殊分选现象的研究成果,以点带面方式分析颗粒流研究的重要进展.同时,本文还分析了颗粒流研究所面临的挑战.
This paper discussed the characters of different granular flow states and the transition mechanisms among different states. Then, it analyzed the stress relationships in granular flow and also gave a summary to the segregation which attracts much interesting in the research of granular flow, and aims to provide important information in this field. Finally, it illustrated the challenges before the research of granular flow, expects to provide help to following research work.
