Abstract:

The scaling design of multi- parallels test section and flow distribution characteristics are studies based on the first wall of water-cooled solid blanket (WCSB) sub-module. Scaling analysis on the structure of first wall is carried out by utilizing scaling law to gain the parameters of test section. Using the method of computation fluid dynamics(CFD), numerical simulation is conducted based on the parameters of test section, and the flow characteristics are analyzed. The results are compared with that of the prototype to verify that the parameters of test section obtained by the scaling method CAD reflect effectively the flow characteristics of the first wall of WCSB sub-module. The research can provide reference for building experimental facility.

Key words: Water-cooled solid blanket, First wall, Scaling analysis, Flow characteristics

摘要：

针对水冷包层子模块并行通道的流量分配对热量导出的影响，以水冷包层子模块第一壁为研究对象，对其并行通道试验段的模化设计与流量分配特性展开了研究。采用模化方法对第一壁的结构进行设计，得出试验段相关参数。采用计算流体力学(CFD)的方法对模化设计的试验段进行数值模拟，并分析其流动状态。将结果与原型结构下的流动特性参数进行比较，验证了采用模化方法得到的试验段参数可以有效反映水冷包层子模块第一壁的流动特点，为试验装置的搭建提供参考。
