Abstract

Abstract

In the experiments performed in HRTL-5,the system was in static instability under some conditions.In this paper,based on the drift flow model,the simulation of flow excursion phenomenon was achieved under HTRL-5 condition.In the same time,the mechanism analysis and the simulation of thermal siphon process were also performed.The result shows that the program can be used to to simulate the static instability of natural circulation system,and the simulation of the excursion phenomenon matches up to the experiment result basically.
