论文摘要
在这里，我们提出了一个新的代码，用于在Tokamak刮擦层（SOL）中对电子动力学进行建模。 Sol-Kit（Scrape-Off层动力传输）是具有动力学（或流体）电子，流体（或固定）离子和扩散性中性的完全隐式1D代码。该代码设计用于对SOL中非本地物理的基本探索，并利用电子分布函数的任意度Legendre多项式分解，同时处理电子离子和电子原子碰撞。我们提出了一种新的方法，可确保非弹性和超弹性碰撞中的粒子和能量保护，以及在Legendre多项式形式主义中对逻辑边界条件的首次完整处理。据我们所知，Sol-Kit是第一个完全隐式的任意程度谐波动力学代码，它提供了一种保守和自洽的方法，可与其集成的流体电子模式进行流体运动比较。在本文中，我们提供了模型方程及其离散化，并显示了许多验证/基准模拟的结果。
Here we present a new code for modelling electron kinetics in the tokamak Scrape-Off Layer (SOL). SOL-KiT (Scrape-Off Layer Kinetic Transport) is a fully implicit 1D code with kinetic (or fluid) electrons, fluid (or stationary) ions, and diffusive neutrals. The code is designed for fundamental exploration of non-local physics in the SOL and utilizes an arbitrary degree Legendre polynomial decomposition of the electron distribution function, treating both electron-ion and electron-atom collisions. We present a novel method for ensuring particle and energy conservation in inelastic and superelastic collisions, as well as the first full treatment of the logical boundary condition in the Legendre polynomial formalism. To our knowledge, SOL-KiT is the first fully implicit arbitrary degree harmonic kinetic code, offering a conservative and self-consistent approach to fluid-kinetic comparison with its integrated fluid electron mode. In this paper we give the model equations and their discretizations, as well as showing the results of a number of verification/benchmarking simulations.
