蒸汽发生器蒸汽限流器流场分析及结构优化

摘要

蒸汽限流器是核电站蒸汽发生器的重要组成部件之一,是确保反应堆安全运行不可缺少的保障措施.对蒸汽发生器出口管嘴蒸汽限流器内的蒸汽流动情况进行了理论研究,利用ANSYS-FLUENT软件对蒸汽限流器进行了流场分析计算,并据此提出了结构优化方案.%The steam restrictor is one of the key components in the steam generator of nuclear power plant, and it is an indispensable guarantee for the safe operation of the reactor.The flow of steam in the steam restrictor of the outlet pipe had been studied theoretically.The flow field of steam restrictor was analyzed and calculated by using ANSYS-FLUENT software,and the structure optimization scheme was put forward.
