摘要: 蒸汽限流器是核电站蒸汽发生器的重要组成部分,是保证反应堆安全运行不可缺少的保障措施。基于CFD数值模拟的方法,对比研究了两种主流文丘里管式蒸汽限流器的流场特征和关键性能。结果表明,十九嘴蒸汽限流器的限流量比七嘴蒸汽限流器高6%,其压力损失也仅为七嘴蒸汽限流器的67.3%。研究结果可为蒸汽限流器的设计和选型提供依据。

Abstract: Stream limiter is an important component of the steam generator in nuclear power plant, which plays a necessary role to ensure the safe operation of the reactor. Based on the CFD numerical simulation method, the flow field characteristics and key performance of two mainstream venturi steam restrictors are compared.The results show that the flow limiting capacity of the nineteen⁃nozzles is 6% higher than that of the seven⁃nozzles,and the pressure loss is only 67.3% of that of the seven⁃nozzles. Research results of this work can be a reference for stream limiter's design and model selection.

Key words: Nuclear power plant, Steam generator, Venturi tube, CFD
