螺旋管内两相流动不稳定性的研究进展综述

浮动核电站是解决我国海上能源供应难题的理想途径。螺旋管直流蒸汽发生器作为核心换热设备,其运行稳定性直接关系反应堆能量输出和安全。文章采用文献调研的方式,针对螺旋管内两相流动不稳定性的国内外研究进展开展综述研究,定性分析海洋条件对于螺旋管内两相流动稳定性的潜在影响,并提出了未来研究中需重点关注的内容。

Floating nuclear power station is an ideal way to solve the offshore energy supply problems in China.As the key heat exchange equipment,the operational stability of the spirally coiled tube type once-through steam generators(OTSGs)can directly affect the reactor energy output and safety.This paper reviews the research progress of two-phase flow instability in spirally coiled tubes based on the published literatures.Potential effects of ocean condition on the of two-phase flow instability in spirally coiled tubes are qualitatively analyzed.Finally,the paper discusses and presents the key points that require attention in future research.
