Numerical Simulation for Two-Phase Flow in First-Stage Moisture Separator of Steam Generator

National Key Laboratory of Reactor System Design Technology, Nuclear Power Institute of China, Chengdu 610041, China

摘要: 采用计算流体力学方法并采用非结构化网格和多块网格技术对流动区域进行了网格划分,用两相流模型对蒸汽发生器一级汽水分离器两相流动进行模拟,得到了汽-液两相流动细节,将出口蒸汽干度与蒸汽发生器热工水力专用计算程序计算结果进行比较,吻合良好。
