摘要: 利用理论公式和CFX仿真分别对偏滤器部件中平板型W/Cu模块进行稳态热分析,获得了不同热流密度下W/Cu模块的温度场和应力场的变化。理论计算得到的对流传热系数约为52304W·(m2·K)‒1,而用CFX仿真分析得到的为35168~52186W·(m2·K)‒1。此外,两种稳态热分析方式得到的W/Cu模块的温度场数值相近;在20MW·m‒2热流密度下,W/Cu模块的温度场、应力场分析结果均超出了对应材料的许用范围,严重影响了偏滤器部件的稳定运行。

Abstract: The steady-state thermal simulation on the flat plate W/Cu module in the divertor was carried out by theoretical formula and CFX software, respectively, and the profiles in temperature and stress fields of the W/Cu module under different heat fluxes were obtained. The convective heat transfer coefficient is about 52304 W·(m2·K)-1 by formula, and is about 35168~52186W·(m2·K)-1 by CFX software. In addition, the temperature profiles of the W/Cu module obtained by the two steady-state thermal analysis methods are similar. Under the heat flux of 20 MW·m2, the results of temperature field and stress field of the W/Cu module are beyond the allowable range of the corresponding materials, which seriously affected the stable operation of the divertor.

Key words: Divertor, W/Cu module, Steady state-thermal analysis, Convective heat transfer coefficient, Finite element simulation
