摘要： 基于颗粒动理学方法,研究了低颗粒浓度气固均匀剪切流流动,建立颗粒压力张量表达式。理论结果表明压力分布呈现各向异性,并且是颗粒弹性恢复系数的函数。计算说明该理论预测的压力分布与Jenkins&Richman的分析结果是一致的。

Abstract: The steady uniform shear flow in a low concentration fluidized gas solid granular flow is studied on the basis of the kinetic theory of granular flow and a modified BGK model equation. Explicit expressions of the pressure tensor are obtained as a function of the restitution coefficient. The computation shows the different normal stresses distribution. The results agree well with the Jenkins Richman theories, although significant discrepancy appears for granular temperature distributions.
Key words: gas solid two phase, shear flow, kinetic theory of granular flow
