采用布朗动力学的计算机模拟方法,研究重力因素对于稀溶液中悬浮粒子聚集过程的影响.通过在计算机模拟程序中加入和排除重力因素的影响,对不同重力条件下的粒子团数量随时间的变化曲线进行对比研究,得到了重力对溶液中的粒子团数和不同大小的粒子团数量随时间变化的影响规律,可以总结为:在聚集阶段初期,重力不影响粒子的聚集;而在聚集阶段后期,重力加快了粒子的聚集.同时,从动力学分析的角度出发,对重力如何影响悬浮溶液中粒子聚集过程的机制也进行了更加深入的探讨. |

The Brownian dynamics method was used to simulate the influence of gravity on the process of particle coagulation in a dilute solution. By including or excluding the gravitational influence in a computer simulation, the relative change in the number of aggregates with time for these two gravitational conditions could be compared. Time-dependent variations of the number and size of all aggregates under the gravitational conditions were obtained. We conclude that the influence of gravity is negligible during the earlier stage of the coagulation process and that the rate of aggregation is accelerated by the gravitational force in the latter stage. The effect of gravitational force on the process of particle aggregation in suspension is discussed by using a dynamic analysis method. |
