摘　　要：空冷岛作为一个空冷电厂的大型换热器,其性能与内外流场密切相关。对空冷岛内部流场进行了系统建模分析,并结合试验进行对比,对空冷岛内部流场的分布规律有了较为深入的理解,为进一步的优化提供了基础。给出了对应于试验结果的空冷岛凝结温度分布的原因及凝结压力分布、凝结流量分配计算结果。As a heater of large scale,the performance of heat transfer of air-cooled condenser in large power plant is closely related to the two side flow field including air flow and steam-water flow.A mathematics modeling systemic analysis and experiment comparison for the large condenser is introduced in this paper,which advances understanding of the steam-water flow field to lay the ground work of optimization.The condense temperature distribution of air-cooled condenser is analyzing and the condense pressure and flux distribution is calculated.
