| 摘 要： | 本文提出了流体诱导振动复合强化传热新方法并进行了实验研究,实验结果表明流体诱导的振动与其他方式一样对传热有足够的影响。弹性管束在流体诱导下的面内振动与面外振动,可以低流速下在提高对流换热系数,降低污垢热阻,使传热效果显著增强。

| Abstract: | A method of heat transfer enhancement by flow-induced vibration was put forward in this paper, and experiments were performed. The results of experiments indicated that flow-induced vibration exerted large influence on heat transfer. The in-surface and out-surface vibrations which come from the flow-induce spring tube bundles, can not only effectively increase the convective heat transfer coefficient, but also decrease the fouling resistance, then increase the heat transfer coefficient remarkably. |

| Keywords: | flow-induced vibration fouling resistance convective heat transfer enhancement |
