Abstract
Stick-slip regime of shear granular flows is studied theoretically and numerically. Numerical experiments are carried out for a thin Couette cell using soft-particle molecular dynamics code in two dimensions. We apply order parameter theory of partially fluidized granular flows and find a good agreement with simulations and experiments by Nasuno et al.
摘要
从理论和数值上研究了剪切颗粒流的粘滑状态。使用二维软颗粒分子动力学代码对一个薄的库埃特流动槽进行了数值实验。我们应用了部分流化颗粒流的序参理论，并发现与Nasuno等人的模拟和实验结果吻合良好。
