| 摘 要： | 提出了胶体颗粒间有引力作用的物理模型,建立了计算机模拟剪切流场中颗粒运动的一套方法,并通过计算机计算模拟了在剪切流场中这种颗粒的运动,计算了不同浓度和不同剪切速率下,整个运动过程中的各种结构参数。根据模拟的结果发现:低浓度下形成的凝聚物是紧密块状的,而高浓度下形成的则是松散网状的。

| Abstract: | A new model, which describes the aggregating kinetics of colloidal particles having an attractive force, is proposed and a corresponding computer simulation scheme is designed. The simulation in shear flow is carried out. Structure parameters are calculated under conditions of various shear rates and concentrations. From the results of the simulations,it is observed that at low concentration compact clusters are formed, while at high concentration loose clusters are formed. |
