摘　　要：对基于多孔介质模型开发的核电蒸汽发生器三维热工水力分析程序ATHOS进行介绍,并应用ATHOS对核电蒸汽发生器二次侧的复杂传热传质现象进行数值模拟。获得蒸汽发生器二次侧的流动换热状态,以及二次侧三维两相流场分布,分析结果可作为传热管流致振动、磨损分析及结构设计的输入数据。研究工作表明,多孔介质模型在核电蒸汽发生器设计中具有重要的应用价值。ATHOS, exploited based on the porous media model, is a software for three-dimensional analysis of the flow and heat transfer in the steam generator of the nuclear power plant. Presents the application of ATHOS by simulating the complex secondary side heat and mass transfer in the steam generator of the nuclear power plant. Through the simulation, obtains the three-dimensional two-phase flow and the temperature field. The result can be used as the input of other researches, such as the analysis of flow induces vibration of tubes, the analysis of wear, the structure design, and so on. The research work of porous media model has valuable application in the design of steam generators in nuclear plants.
