刚球粒子碰撞频率和距离关系的计算机模拟(英文)

Dependence of Collision Frequency on Distance between Two Hard-sphere Particles Estimated by Computer Simulation

用Monte Carlo方法模拟了由两个刚球粒子组成的体系,得到了碰撞频率和粒子间距的定量关系。模拟结果显示,碰撞频率随着粒子间距的增大急剧下降。这一特性为文献[1]中描述的两个粒子体系的聚集过程的碰撞反应动力学提供了有用的旁证。

A Monte Carlo simulation is performed to study the dependence of collision frequency on interparticle distance for a system composed of two hard-sphere particles. The simulation quantitatively shows that the collision frequency drops down sharply as the distance between two particles increases. This characteristic provides a useful evidence for the collision-reaction dynamics of aggregation process for the two-particle system described in Ref. ([1]).
