SOLPS模拟一个专用的ASDEX升级欧姆拍摄的刮削层和偏滤器建模。的倾向的代码来预测一个更冷，更密集的偏滤器等离子体的实验相比，满足主要边界条件（输入功率的核心/边缘边界，粒子吞吐量和辐射功率）和匹配的上游配置文件的解决方案被确认。讨论了与中性源和汇的作用有关的问题。在基于实验性上游剖面的解释性建模中，发现偏滤器中的中性压力和加料方法都不会对外部目标处的参数产生强烈影响，这些参数主要由输入功率和分界线密度决定。
SOLPS simulation of a dedicated ASDEX Upgrade Ohmic shot for scrape-off layer and divertor modelling is described. The tendency of the code to predict a colder and denser divertor plasma compared with the experiment for solutions that satisfy main boundary conditions (on the input power across the core/edge boundary, particle throughput and radiated power) and match upstream profiles is confirmed. Issues related to the role of neutral sources and sinks are discussed. In the interpretative modelling based on experimental upstream profiles, neither the neutral pressure in the divertor nor the method of fuelling was found to strongly influence the parameters at the outer target, which are primarily determined by the input power and separatrix density.
