| 摘 要： | 用9种不同规格的试验管,在大气压力下的饱和水及乙醇中进行了系统的实验。结果表明,安装角对管外池沸腾传热性能有明显的影响。倾角增加,汽泡扰动加剧,沸腾换热强度增大。综合524组实验数据,得到包括倾角、长径比在内的管外池沸腾传热准则关系式,可供工程设计时预测倾斜管沸腾传热系数。

| Abstract: | The present paper discribes experiment research of effect of the inclination on heat transfer on 9 kinds of plain tubes in atomosphere, working fluids are distill water and ethanel. Experinent result show very obvious effect of inclination of pool boiling heat transfer. The larger heat transfer increases, the larger the inclination does. The correlation obtained on 524 experiment data can be used for reference to engineering design in prospect of heat transger coefficient. |

| Keywords: | pool boiling inclination bubble disturbance enhance heat transfer |
