本文针对以载流线圈(其中大部分线圈或全部线圈的电流是由等离子体电流感应产生的)维持平衡的环流器(托卡马克)系统,提出了一种基于等离子体-线圈的互感作用原理,并将格林函数法和有限差分法配合使用的自由边界磁流体平衡的数值计算方法.这个方法考虑了限制器对位形的影响。用这种方法,对一个线圈成形的非圆截面环流器装置系统进行了实验所需的许多自由边界平衡位形计算,得到了类椭圆、肾形、双流器等非圆截面位形。在此基础上,分别考察了等离子体电流分布,限制器位置、β_p 值、线圈运行方式和回路外加元件参数等诸因素对等离子体平衡位形的影响。
In this paper, we present a cyclostat (Tokamak) system that maintains a balance of current-carrying coils in which most of the current in the coils or all of the coils is induced by the plasma current and proposes a plasma-coil based mutual inductance principle , And the numerical calculation method of the free boundary magnetic fluid balance which is combined with the Green function method and the finite difference method is adopted.The method considers the influence of the limiter on the shape of the shape. In this method, a lot of free-boundary equilibrium configurations are calculated for a coil-shaped non-circular cross-section circulator device system. The elliptical, kidney-shaped and double-flow devices are obtained. On this basis, the influence of the plasma current distribution, the position of the limiter, the value of β_p, the operating mode of the coil and the additional components of the loop on the plasma equilibrium configuration were investigated respectively.
