We present the first parallel electron transport results obtained using the newly developed 1D transport code SOL-KiT. With the capability to switch between consistent kinetic and fluid models for the electrons, we explore and report the differences in both equilibrium and transient simulations. Significant kinetic effects are found during transients, especially in the behaviour of the electron sheath heat transmission coefficient, which shows up to an eightfold increase. Equilibria are obtained for an input power scan with parameters relevant to medium size tokamaks. Detached equilibria are found to persist to higher input powers when electrons are treated kinetically. Furthermore, non-monotonic behaviour of the electron sheath heat transmission coefficient is observed in the power scan, with values being up to 40% above the classical value. We discuss the implications of the presented results to potential modelling decisions, as well as possible extensions to the used model.

刮层中平衡和瞬变期间平行电子传输的动力学和流体模拟

我们展示了使用新开发的一维传输代码SOL-KiT获得的第一个平行电子传输结果。具有在电子的一致动力学模型和流体模型之间切换的能力，我们探索并报告了平衡和瞬态仿真中的差异。在瞬态过程中发现了显着的动力学效应，尤其是在电子鞘层传热系数的行为方面，这种行为表现出高达八倍的增长。对于具有与中等大小托卡马克有关的参数的输入功率扫描，可以获得平衡。当对电子进行动力学处理时，发现分离的平衡将持续存在较高的输入功率。此外，在功率扫描中观察到电子鞘层传热系数的非单调行为，其值比经典值高40％。
