| 摘 要： | 单头“W”形螺旋槽管是在螺旋槽管的基础上开发出的一种新型强化管。本文研究了各种结构参数对流动和紊流换热特性的影响,从理论上探讨了其强化传热机理,并和实验结果进行了比较,结果表明此管的性能明显优于光滑管,在p/e=10～14范围内且具有小螺距和适当槽深的单头“W”形螺旋槽管的综合性能是最优的。

| Abstract: | We research into a new heat transfer enhanced tube-unusual spirally fluted tube developed from spirally corrugated ones. Various geometrical parameters of effecting heat transfer and flow are analyzed; theoretically the mechanisms of heat transfer are discussed and experimental results are compared. The results show that comprehensive performance of "W" type spirally fluted tube is better than that of smooth tube.and the comprehensive performance of "W" type spirally fluted tube with P/e=10- 14 and with minor flute pitch and proper flute depth is excellent. |
