Simulation of flow excursion and thermal siphon under natural circulation condition with lower pressure and lower quality

Abstract

The simulation of flow excursion was conducted under HRTL-5 condition. The mechanism analysis and the simulation of thermal siphon process were also performed. The result shows that the computer code can be used to simulate the static instability of a natural circulation system and the simulation of flow excursion almost conforms to the experiment result.
