摘要

采用凝汽器壳侧汽相流场与传热特性的数值计算方法对２００ＭＷ．间接空冷汽轮机组表面式凝汽器管束布置的三个改进方案进行了分析比较。根据蒸汽－空气混合物的速度、压力、空气浓度、传热系数及热负荷等重要参数分布的计算结果讨论了管束布置方式对流动与传热的影响。最后，推荐了一个较合理的方案。

Abstract

Analysed and compered in this Paper are three variant designs of condenser tube arrangement for a 200￣MW tulbine with air cooling through numerical calculation of steam flow field and heat transfer in condenser. The influence on the flow and heat transfer by tube arrangement has been studied

based on calculated distribution of main parameters such as velocity and pressure of steam air mixture

air concentration

heat transfer coefficient and heat load

and a more rational design is recommended.
