摘　　要：文章运用专业的凝汽器数值仿真分析软件对目前600 MW等级汽轮机凝汽器常用的几种典型管型结构进行了数值仿真计算,对凝汽器不同管型结构的几何模型、压力场、空气浓度场、传热系数分布场、速度矢量场进行了深入的对比分析,并在此基础上综合评估了各管型结构热力性能的优缺点,为进一步凝汽器管型优化提供了理论依据。Through the professional condenser numeral simulation analysis software, the numerical analysis and calculation for several condenser tube bundles arrangement of 600 MW steam turbine has been provided in detail. Based on the deep analysis of the geometric model, the pressure field, the air concentration field, the heat transfer coefficient field and the velocity vector distribution, the merits and drawbacks of these tube bundles have been estimated which have provided the theoretical basis for further condenser tube bundles arrangement optimization.
