摘要:

运用数值模拟程序B2.5-EIRENE对偏滤器进行了概念设计和优化,通过优化偏滤器靶板的几何结构影响中性粒子的再循环和热沉积面积,继而影响偏滤器靶板上沉积的热负载。通过对两种偏滤器靶板的几何结构的模拟,重点分析了偏滤器靶板上沉积的热负载,靶板上沉积的总热通量和电子、离子热沉积分布,以及真空室第一壁上电子、离子和总热沉积分布等参数。

Abstract:

The numerical simulation code of B2.5-EIRENE is used to design and optimize of the divertor target plates. The divertor targets geometrical structure influences the neutrals recycling and surface area of the heat loads on the target plates, and further influences the heat loads on the target plates. New designed divertor structures are assessed through analyzing the peak heat loads and the electron and ion heat flux on the target plates, the distribution of total heat loads along the target plates and first wall of the main vacuum chamber.

Key words: B2.5-EIRENE, Numerical simulation, Heat flux analysis
