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·(m^(2)·K)^(‒1),而用CFX仿真分析得到的为35168~52186W·(m^(2)·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。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·(m^(2)·K)^(−1)by formula,and is about 35168~52186W·(m^(2)·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·m^(-2),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.
