TEXTOR-DED中边缘遍历等离子体的传输特性（Finken K H和Wolf G H 1997 Fusion Eng. Des. 37 337）进行了研究，使用三维等离子体边缘传输程序包，EMC 3-EIRENE，在即将到来的实验活动。EMC 3解决了稳态等离子体流体方程的质量，动量和能量，在几乎任何任意的3D磁性和边界表面配置。它是迭代耦合EIRENE，一个三维动力学中性粒子输运代码。已经选择了两个不同的遍历水平，以评估边缘等离子体传输的遍历性的额外影响。该代码预测了一个显着的变化，在径向分布的电子温度为更高的遍历和等离子体流场和磁场结构之间的显着的相关性。的作用（最外层）的“层流区”上的能量沉积模式到偏滤器进行了分析。它被发现，它的影响敏感地依赖于遍历实现的程度。
Transport properties of the edge ergodized plasma in TEXTOR-DED (Finken K H and Wolf G H 1997 Fusion Eng. Des. 37 337) are studied using the 3D plasma edge transport code package, EMC3-EIRENE, prior to the forthcoming experimental campaign. EMC3 solves the steady-state plasma fluid equations of mass, momentum and energy, in almost any arbitrary 3D magnetic and bounding surface configurations. It is iteratively coupled with EIRENE, a 3D kinetic neutral particle transport code. Two different levels of ergodization have been selected in order to assess the additional effects of ergodicity on edge plasma transport. The code predicts a significant change in the radial profile of electron temperature for the higher ergodization and a pronounced correlation between the plasma flow fields and the magnetic field structure. The role of the (outermost) 'laminar zone' on the energy deposition pattern onto the divertor is analysed. It is found that its influence depends sensitively on the degree of ergodization achieved.
