Part 1 described a wide range of analytic tokamak equilibria modelling smooth limiter surfaces, double- and single-null divertor surfaces, arbitrary aspect ratio, elongation, triangularity and beta. Part 2 generalizes the analysis to further include edge pedestals and toroidal flow. Specifically, edge pedestals are allowed in the pressure, pressure gradient and toroidal current density. Also, an edge-localized contribution to the bootstrap current is treated. In terms of flow, analytic solutions are obtained for two cases: a $\gamma = 2$ adiabatic and a $\gamma = \infty $ incompressible energy conservation relation.

简单、一般、现实、稳健、解析的托卡马克均衡。第 2 部分。基座和流量

第 1 部分描述了广泛的分析托卡马克平衡建模光滑限制器表面、双零和单零偏滤器表面、任意纵横比、伸长率、三角形和 beta。第 2 部分概括分析以进一步包括边缘基座和环形流。具体来说,允许在压力、压力梯度和环形电流密度中使用边缘基座。此外,还处理了对自举电流的边缘局部化贡献。在流动方面,得到了两种情况的解析解: $\伽马 = 2$ 绝热和 $\gamma = \infty $ 不可压缩能量守恒关系。
