摘要:

本文描述了用于碰撞玻尔兹曼方程确定性模拟的方法。假设方程中的输运和碰撞部分在时间域内分别进行模拟。回顾了实现分裂的时间步进格式以及算子每个部分的数值方法,重点清晰地揭示了方程带来的挑战以及各种方案对其的解决。

英文摘要:

This article describes methods for the deterministic simulation of the collisional Boltzmann equation. It presumes that the transport and collision parts of the equation are to be simulated separately in the time domain. Time stepping schemes to achieve the splitting as well as numerical methods for each part of the operator are reviewed, with an emphasis on clearly exposing the challenges posed by the equation as well as their resolution by various schemes.
