摘要

通过数值计算对湿工况下的H型和圆型翅片管换热器通道内充分发展段的对流冷凝传热特性进行模拟研究。计算采用压力与速度耦合的SIMPLER算法，湿烟气流速范围为1~5 m/s，水蒸气质量分数范围为5%~13%。讨论了不同入口速度、水蒸气质量分数对H型翅片管和圆型翅片管传热传质系数、传热量、冷凝水流量和翅片效率的影响，并进行定量比较分析。计算结果表明，H型翅片管的传热能力强于圆型翅片管，但冷凝生成量较圆型翅片管小，同时H型翅片管的总翅片效率和潜热翅片效率小于圆型翅片管。

Abstract

The numerical simulation is used to simulate the convective condensation heat transfer characteristics of the fully developed section of the H-type and round fin-tube heat exchanger channels under wet conditions. The SIMPLER algorithm is used to calculate the pressure and velocity coupling. The wet flue gas flow rate ranges from 1 to 5 m/s

and the water vapor mass fraction ranges from 5% to 13%. The effects of different inlet velocity and water vapor mass fraction on heat and mass transfer coefficient

heat transfer

condensate flow rate and fin efficiency of H-shaped finned tube and circular finned tube were discussed. The calculation results show that the heat transfer capacity of H-type finned tube is obviously stronger than that of circular finned tube

but the condensation production is less than that of circular finned tube. Meanwhile

the total finned efficiency and latent heat finned efficiency of H-type finned tube are less than that of circular finned tube.
