本文提出了一个模型的等离子体边界区，已开发的研究杂质的流动产生的目标板在抽运偏滤器配置计划喷气发动机。对于流动方程的模型是一维的，平行于磁场，但中性物种是在两个维度。杂质的所有电离阶段都可以单独处理，或者可以考虑平均电荷杂质物质。这种近似的有效性进行评估。所提出的结果表明，杂质可以保留在附近的目标板的强制流动的等离子体产生的再循环，跨越分界线从主等离子体的刮除层，一小部分的流量到达目标板。
The paper presents a model of the plasma boundary region that has been developed to study the flow of impurities generated at the target plates in the pumped divertor configuration planned for JET. For the flow equations the model is one-dimensional, parallel to the magnetic field, but the neutral species is treated in two dimensions. All ionization stages of an impurity can be treated separately or, alternatively, an average charge impurity species can be considered. The validity of this approximation is assessed. The presented results show that impurities can be retained near the target plates by a forced flow of plasma generated by recirculating, across the separatrix from the main plasma to the scrape-off layer, a fraction of the flow reaching the target plates.
