摘　　要：在探测器超导磁体的低温系统预研中,搭建了小型的氦虹吸冷却回路实验系统,进行了气-液两相沸腾和传热特性实验研究,并利用VOF多相流模型模拟计算了氦的热虹吸自然冷却循环过程和过热烧干过程。在相同条件下,模拟计算结果与实验数据进行了比较,模拟计算得到的的温度分布、璧面过热度与实验测量数据符合度较好。In the process of the cryogenic cooling system pre-study of a detector superconducting magnet at IHEP-China, a small experiment system HeI thermosiphon cooling circulation loop was built, the gas/liq- uid two-phase boiling and heat transfer characteristics was mvestigated experimentally, and the fluid （VOF） model in FLUENT14.0 was used to simulate natural cooling circulation process and superheating dryout process in a thermosyphon respectively. The simulation results were compared with experimental measure- ments in the same condition. The temperature distribution and the wall superheat obtained by CFD are in good agreement with experimental data.
