Investigation of Enhanced Condensation Heat Transfer outside Vertical Titanium Circularly-Grooved Tube

College of Power and Nuclear Energy Engineering Harbin Engineering University, 150001, China

摘要: 对钛波槽管进行了垂直管外凝结换热的实验研究。通过实验得出结论:钛波槽管具有良好的强化传热效果;在实验范围内,最佳钛波槽管的总传热系数是钛光管的1.12～1.36倍。通过对实验数据的回归分析,得到了管内对流换热、管外凝结换热及流动阻力系数的实验关联式。

Abstract: The investigation of enhanced condensation heat transfer had been conducted on the outside vertical Titanium circularly-grooved tube.The experimental result indicates that the Titanium circularly-grooved tube is fairly efficient in enhancing the heat transfer.Within the experimental scope,the total heat transfer coefficient of the optimum circularly-grooved tube is 1.12 to 1.36 times of that of the Titanium smooth tube.Through regression analysis on the experimental data,the experimental correlations for the in-side heat transfer coefficient,the condensation heat transfer coefficient on film condensation and the friction coefficient were achieved.
