| 摘 要： | 通过ANSYS CFX对ITER屏蔽块进行了热工水力分析，对同一计算模型给出了两套不同的网格，分析了网格对计算精度的影响，结果表明两套网格都有较好的计算精度。通过数值模拟分析了壁面粗糙度对流动及传热的影响，结果表明壁面粗糙度是影响传热的一个非常重要的因素。

| Abstract: | Thermal-hydraulic analysis was performed for ITER shield block using CFD code ANSYS CFX. Two different types of computational meshes were given for the same numerical model, the effect of meshes on the numerical precision was studied in the simulation and it indicated that there is good numerical accuracy for the two types of meshes. The effect of wall roughness on the flow and heat transfer was studied through numerical simulation; the results show that it is an important element for wall roughness in heat transfer computation. |
