摘要：

随着工业的发展，液化石油气储存的安全问题越来越重要。油气球形储罐泄漏以沸腾液体膨胀蒸汽爆炸（BLEVE）为主，严重影响着工作人员的安全。因此研究不同曲率曲面沸腾过程，快速降低传热系数（HTC）十分关键。研究了四种不同曲率曲面对于沸腾的影响，并对气泡的传热特性和动力学进行讨论。研究结果表明：除了曲率为47^-1 mm^-1的表面，其余表面传热系数随着曲率的增大不断增大。相较于平面沸腾，曲面沸腾实现了气泡的定向输运，加快了表面气泡的更新速率，从而提高了沸腾过程中的临界热通量（CHF）和传热系数，其中曲率为47^-1 mm^-1的曲面圆心角0°处CHF最高，为138.8 W/cm²，相较于光滑平表面升高了26.2 %，其对应的表面温度为111.4 ℃。

Abstract:

With the development of industry, the safety problem of liquefied petroleum gas storage is becoming more and more important. The leakage of oil and gas spherical storage tank is mainly caused by boiling liquid expansion vapor explosion (BLEVE), which seriously affects the safety of workers. Therefore, it is very crucial to study boiling process on different curved surfaces and quickly reduce the heat transfer coefficient (HTC). The influence of four different curved surfaces on boiling was investigated, and the heat transfer and dynamics of bubbles were discussed. The results show that except for the surface with a curvature of 47^-1 mm^-1, the heat transfer coefficient of other surfaces continuously with the increase of curvature. Compared with plane boiling, curved surface boiling achieves the directional transport of bubbles, speeds up the renewal rate of surface bubbles, and thus the critical heat flux density (CHF) and heat transfer coefficient in the boiling process. Among them, the CHF at the center angle of 0° of curved surface with a curvature of 47^-1 mm^-1 is the highest, which is 138.8 W/cm², an increase of 26.2 % compared with the smooth plane surface, and the corresponding surface temperature is 111.4 ℃.
