摘　　要：以某机组凝汽器为研究对象,分别对AT型和UT型两种不同管束布置利用STAR-CD分析软件建模并进行壳侧性能分析,得到凝汽器内部的流场和压力分布、管束区换热系数和凝结率及汽气混合物分布情况,以便对管束布置进行优化,提高凝汽器整体性能。Taking the condenser of a certain unit as the research object,AT type and UT type tube bundles are respectively modeled by STAR-CD and the shell side performance is analyzed.The flow field and pressure distribution,heat transfer coefficient and condensation rate in the tube bundle area and the distribution of steam-gas mixture in the condenser are obtained,so as to optimize the tube bundle layout and improve condenser performance.

关 键 词：凝汽器 管束布置 性能分析
