| 摘 要： | 为了研究蒸汽发生器干燥器的负荷分布特性,采用计算流体动力学(CFD)软件ANSYS CFX12.1,对CPR1000蒸汽发生器干燥器进行单相流场分析,得到其流场分布,对干燥器的负荷不均匀性及分离性能进行了评估分析。此外,通过与无均汽网模型的计算结果进行对比,分析均汽网对于干燥器负荷分布及分离性能的重要性,并提出了均汽网设计的改进方法。

| Abstract: | In order to investigate the flow distribution of dryers, single-phase CFD analysis is carried out to evaluate the single-phase performance analysis of dryers in CPR1000 steam generator. The distribution of flow-field is achieved for the analysis of the flow mal-distribution and separation performance evaluation of dryers. At the same time, the results of the model without dryer inlet grids are compared and the importance is investigated. Finally, the suggestions for improving the performance of dryer inlet grids are brought forward. |
