Orbit-averaged Guiding-center Fokker-Planck Operator
摘要:
本文提出了一种适用于轴对称磁化等离子体输运过程数值分析的广义轨道平均导向中心Fokker-Planck算符。轨道平均导引中心算符描述了三维导引中心不变空间中的输运过程:轨道平均磁通不变$\ovψ$、最小B节距角坐标$ξ_{0}$和动量大小$p$。
英文摘要:
A general orbit-averaged guiding-center Fokker-Planck operator suitable for the numerical analysis of transport processes in axisymmetric magnetized plasmas is presented. The orbit-averaged guiding-center operator describes transport processes in a three-dimensional guiding-center invariant space: the orbit-averaged magnetic-flux invariant $\ovψ$, the minimum-B pitch-angle coordinate $ξ_{0}$, and the momentum magnitude $p$.
