Development of U Tube Steam Generator Model and Its Simulation

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.
