Abstract

Abstract:

A new water-cooled tungsten lower divertor was designed to replace the present carbon lower divertor in EAST to fit the heat flux up to 10MW·m^-2under a 400s long pulse and high β H-mode plasma operation. Based on the heat transfer simulation of the lower divertor, an advanced water-cooled structure for the lower divertor was proposed after several cooling structures were studied. According to the analysis, the divertor model of EAST which meets the requirements of heat transfer is established.

Key words: EAST, Plasma, Tungsten divertor, Water-cooled, Heat transfer

摘要：

为实现EAST装置超400s长脉冲高约束模、10MW加热功率下的稳态运行，需对现有的下碳偏滤器进行升级改造，拟采用钨串结极水冷却系统，热通量控制在水冷钨铜第一壁材料允许的稳态的10MW·m^-2。在对下钨偏滤器的冷却结极传热性能进行数值模拟仿真研究的基础上，研究了多种以钨串单元为基础的冷却结极，提出了一种新型下钨偏滤器水冷结极设计，幵建立了满足传热要求的EAST装置新型下钨偏滤器单元结构模型。
