| 摘 要： | 基于基本的流体质量、能量和动量守恒原理，建立了套管式直流蒸汽发生器的动态数学模型。该模型采用集总参数和移动边界的建模方法，将直流蒸汽发生器流道分为欠热段、沸腾段和过热段。采用Gear算法求解，对建立的模型进行稳态和动态仿真，并利用RELAP程序进行校验。结果表明：所建立的模型是正确和有效的，能用来进行直流蒸汽发生器的动态特性实时仿真。

| Abstract: | Based on the conservation equations of mass,energy,and momentum,the mathematical model of once-through steam generator(OTSG)with concentric annuli tube was developed by lumped parameters with moving boundary.The heat transfer section of OTSG was divided into three regions:subcooled,nucleate boiling and superheat regions.The stable and dynamic simulations were analyzed by Gear method.The results show that the developed model and code are accurate,effective and can be used to simulate the steam generator dyna... |
