摘　　要：对直接空冷凝汽器蛇形翅片单排管外侧空气流动与传热特性进行了研究,利用FLUENT软件对翅片空气侧流动和传热性能进行数值模拟,分析了不同来流风速和翅片长度对传热系数和压力损失的影响,为空冷凝汽器传热元件的设计与优化提供数据支持。Flow and heat transfer characteristics at air side of single-row wavy-finned tubes for directly air-cooled condensers were studied. Numerical simulation on above flow and heat transfer characteristics was carried out using software FLUENT, while influence of air speed and fin length on the heat transfer coefficient analyzed. This may serve as a reference for design and optimization of heat transfer elements for air-cooled condensers
