摘要
螺旋槽管对强化管的强化换热性能影响有换热和流动两个方面,为了综合评价螺旋槽管的性能,结合前人的研究成果推导出了螺旋槽管的性能评价准则,得出了螺旋槽管的性能系数(PEC),并应用评价准则对两组螺旋槽管进行了性能分析。
Spirally fluted tubes impact the heat transfer performance of strengthen tubes on heat exchange and flow aspects. In order to evaluate the performance of spirally fluted tubes, this paper deduces the performance evaluation criteria of spirally fluted tubes based on previous research findings and applies the performance evaluation criteria to evaluate the performance of two groups＇ spirally fluted tubes.
