| Abstract: | Serrated spiral-finned-tube,developed from solid spiral-finned-tube,has been widely applied in large-scale heat-exchange facility due to its advantages such as easier manufacture,more extended heat transfer surfaces,higher heat transfer coefficient and fin efficiency.For the effects of fin pitch on heat transfer and flow resistance of serrated spiral-finned-tube banks(SSBs),nine SSBs with staggered layouts in terms of various fin pitch were tested based on the analysis on its influencing mechanism.The exper... |
