小汽机表面式间冷散热器流动和传热数值研究

摘要

To solve actual engineering problems, the flow and thermal characteristics of air cooling tower used indirect air cooled radiator under natural draft is simulated and analyzed by using the numerical heat transfer (NHT) software called FLUENT. The influence of different wind speeds on the natural draft rate of the tower and heat transfer rate of air cooled radiator are identified. It offers a theoretic foundation for the optimal design of indirect air cooling system.%针对实际工程问题,利用计算传热学(NHT)软件FLUENT,对自然通风状态下,某表面式间接空冷散热器空冷塔的流动和换热性能进行了数值模拟、分析和研究.确定了不同环境风速对空冷塔通风量和间接空冷散热器散热量的影响,为间接空冷系统的优化设计提供理论依据.
