子体模拟

对于各个计算组织，等离子体的模拟一直是个极大的挑战，有很多不同近似程度的模拟计算方法。包括完整的动力学计算方法，流体近似方法和关于漂移扩散方程的方法。近几年来，有人用Fokker-Planck方程处理等离子体中的电子，同时把离子当作流体进行耦合计算，获得了很好的计算结果。本章我们将介绍基于通用Fokker-Planck方程的计算求解过程，并通过一个具体实例得到电容放电过程的电子密度分布。希望通过该简单模型使读者对等离子放电建模过程有个初步的了解。-The sub-body simulations for various computing organizations, the simulation of the plasma has been a great challenge, there are many different approximate degree of simulation methods. Including the full dynamics calculation method, the fluid approximation method and on the drift-diffusion equation. In recent years, some people use the Fokker-Planck equation to deal with the electrons in the plasma, ions as a fluid coupling calculation to get a good calculation. In this chapter we will introduce the generic Fokker-Planck equation-based computing solution process, and through a concrete example of the distribution of electron density of the capacitor discharge process. Plasma discharge modeling process has a basic understanding of the reader through the simple model.
