三维边缘等离子体输运代码EMC3-EIRENE[1]成功地适应了JET的单零配置。准备了一个具有完善的2D边缘等离子体代码EDGE2D-EIRENE[2,3]的测试平台，以检查EMC3-EIRENE代码的适应性，并在比较时隔离任何差异。虽然这两种代码本质上都解决了相同的一组简化Braginskii流体方程，但它们使用了非常不同的数值技术：EMC3中的三维拉格朗日蒙特卡罗方法和EDGE2D中的二维欧拉有限差分格式。结果应该是非常相似的，因为这两个代码迭代耦合到相同的动力学中性粒子蒙特卡罗代码EIRENE[4]。我们表明，这两个代码在背板和目标等离子体剖面以及随着核心等离子体密度的增加从低到高循环状态的转变方面具有相当好的定量一致性。
The 3D edge plasma transport code EMC3-EIRENE [1] was successfully adapted to the single null configuration of JET. A test bed with the well established 2D edge plasma code EDGE2D-EIRENE [2,3] was prepared to check the adaptation of the EMC3-EIRENE code and isolate any discrepancies when compared. While both codes solve essentially the same set of reduced Braginskii’s fluid equations, they use very different numerical techniques: a 3D Lagrangian Monte Carlo method in EMC3 and a 2D Eulerian finite differences scheme in EDGE2D. The results should be very similar as both codes are iteratively coupled to the same kinetic neutral particle Monte Carlo code EIRENE [4]. We show that both codes are in a fairly good quantitative agreement regarding both midplane and target plasma profiles as well as transition from low to high recycling regime with increasing core plasma density.
