摘　　要：根据船舶饱和蒸汽系统管道的工作特点和结构特点,将复杂的蒸汽管网分为大直径蒸汽管道和小直径蒸汽管网两类仿真对象,根据质量守恒、能量守恒定律针对这两类仿真对象分别建立了两相箱体模型和流体网络模型。考虑了流体网络中网络节点与外界环境的散热,提出了流体网络节点压力、温度、焓的修正方法。在某核动力装置模拟器上进行的仿真实验表明,该模型能够较好地反映船舶饱和蒸汽系统管道运行的动态特性。The pipes of steam system of marine were divided into two kinds of simulation objects by their different working and structure characteristics： long diameter steam pipes and steam flow net of short diameter. The two-phase tank model and the flow net model were set up based on mass and energy conservation for these two simulation objects respectively, Considering the emission of heat from nodes of flow net to enviroriment, a correcting method was proposed for pressure, temperature and enthalpy of nodes of flow net model. These models were successfully applied to a simulator of marine nuclear powered equipment, and the results of simulation tests indicate that the mathematical model can reflect exactly the dynamic characteristic of pipes of steam system of marine.
