摘　　要：为了研究凝汽器流动与传热特性沿轴向的变化，文中发展出一个凝汽器汽相流动与传热特性的准三维数值计算方法，应用该方法对一大型凝汽器汽相流动与传热特性进行了数值模拟．计算结果表明，单流程凝汽器冷却水温度沿流向的变化对蒸汽流动与传热的三维特性会产生明显的影响．A quasi three dimensional numerical method is developed for predicting the steam flow and heat transfer behavior of condenser. It is applied to a one pass large power plant condenser. The calculation results show that the variation of cooling water temperature along the flow direction has significant effects on the three dimensional pattern of steam flow and heat transfer.
