Abstract

Abstract:

A HEMJ unit (He-cooled divertor with multiple-jet cooling) is simulated and analyzed by ANSYS/CFX under the same heat load but different cooling conditions. Temperature and surface convective heat-transfer coefficient field was obtained and is taken as the loading conditions for thermal mechanical analysis. Thermal mechanical analysis is performed by ANSYS/Mechanical under steady-state conditions for HEMJ units. Stress distributions of divertor structures with different structural parameters were achieved. And the influence of the changeable structural parameters on thermal stress is analyzed and filtered to acquire a design with lower thermal stress than the orignal one. And finally an optimal design was obtained.

Key words: Helium-cooled divertor, ANSYS, Temperature field, Stress field

摘要：

利用ANSYS/CFX对聚变堆氦冷多喷嘴冷却偏滤器模块在相同高热负荷条件但不同冷却条件下进行了有限元数值分析，得到了偏滤器冷却单元的温度和换热系数分布图，将该温度场作为结构力学分析的加载条件，利用ANSYS/Mechanical对冷却模块进行了稳态条件下的结构应力分析，得到了具有不同结构参数的偏滤器模块的应力分布。通过分析各结构参数对偏滤器模型的热应力的影响，对结构参数进行筛选，得到内应力相对较低的结构设计，从而优化多喷嘴氦冷偏滤器结构。
