连续介质中的跳跃和合并:数值研究

Jumps and Coalescence in the Continuum: a Numerical Study

Kozitsky Yuri, Omelyan Igor, Pilorz Krzysztof

摘要:

研究了跳跃和聚结点粒子的无限连续系统的动力学。在跳跃过程中,粒子相互排斥,而它们的聚结是自由的。作为运动方程,我们采取的动力学方程,从对应于这种运动的微观Fokker-Planck方程通过标度过程导出。本文的结果是数值研究(由龙格-库塔法)的动力学方程的解决方案,揭示了一些有趣的特性的动态和澄清的特殊作用的跳跃和合并系统的演变。还发现并分析了可能的非平凡定态。

英文摘要:

The dynamics is studied of an infinite continuum system of jumping and coalescing point particles. In the course of jumps, the particles repel each other whereas their coalescence is free. As the equation of motion we take a kinetic equation, derived by a scaling procedure from the microscopic Fokker-Planck equation corresponding to this kind of motion. The result of the paper is the numerical study (by the Runge-Kutta method) of the solutions of the kinetic equation revealing a number of interesting peculiarities of the dynamics and clarifying the particular role of the jumps and the coalescence in the system's evolution. Possible nontrivial stationary states are also found and analyzed.
