摘要
建立了压水堆核动力装置蒸汽发生器的数学模型,该模型包含15个控制体,其中12个控制体是边界可移动的控制体,在模型运行中这些控制体可以随工况变化,可以消失,也可以重新出现。模型的建立基于严格的守恒定律,其内部所有的工质流动和传热都可以改变方向。最后对该模型进行了仿真研究,仿真试验结果表明蒸发器模型较全面地反映了其内部的动态热工水力过程。
A mathematical model of U Tube steam generator is developed in this paper, the model contains 15 control volumes,some of them can go to disappear and reappear. The model depends completely on conservation laws. The directions of the fluid flows and heat transfers could be reversed. Then, the model is applied to make some simulation tests. The results show that the model is capable of simulating properly the dynamic response of U tube steam generator.
