Bohm模式下氘氚燃烧等离子体的动态稳定性数值计算

Numerical Analysis on the Dynamic Stabilization of D-T Burning Plasma for the Bohm Type

采用Grank Nicholson差分方法 ,应用循环迭代 ,对氘氚燃烧的等离子体的动态稳定性进行了数值分析 .研究中采用了Bohm模式的热传导率 ,考虑了α粒子的反常扩散效应 ,电子和离子有不同的温度 .考虑了动态反馈加热 ,使等离子体实现了稳态燃烧 .数值分析结果与理论模型预言相一致 .

By Grand-Nicholson difference method and iteration, numerical analysis on the dynamic stabilization of D-T burning plasma is performed.The Bohm type thermal conductivity,the α particle anomalous diffusion and the different temperatures of electron and ion are considered in this paper.In order to sustain D-T steady state burning,the dynamic feedback heating power must be presented,otherwise,the burning would be extinguished.The results of numerical analysis are consistent with the theoretical prediction.
