本文介绍了托卡马克边缘等离子体二维多组分流体模拟程序B2.5，并应用于ITER和TPX中杂质籽晶效应的参数研究。我们的建模表明，ITER必须在约6.0 × 1019/m3的边缘密度和扩展性能TPX必须在约5.0 × 1019/m3的边缘密度操作，以获得一个强大的偏滤器解决方案的基础上，从边缘等离子体的杂质辐射只有在氖浓度低于0.6%或氩浓度低于0.4%。对于这两种装置，依赖于来自核心和边缘的杂质辐射的高再循环偏滤器解决方案似乎非常可信。
The B2.5 code for two-dimensional multi-species fluid modelling of the tokamak edge plasma is described and is applied for a parameter study of the effect of impurity seeding in ITER and TPX. Our modelling indicates that ITER must operate at an edge density of about 6.0 x 10 19 /m 3 and the extended performance TPX must operate at an edge density of about 5.0 x10 19 /m 3 in order to obtain a robust divertor solution based on impurity radiation from the edge plasma only at neon concentration below 0.6% or argon concentration below 0.4%. For both devices, a high-recycling divertor solution relying on impurity radiation from core and edge together appears very credible.
