摘要

摘要: 在自然循环实验台架上进行窄矩形通道自然循环流量漂移实验研究。当加热到一定功率时,系统开始出现自然循环流量漂移,且流量漂移过程中伴随着流量振荡;整个系统的稳定性随着入口流体欠热度、压力、缝隙宽度的增加而增大。通过欠热度数、相变数等参数绘制出系统的稳定性曲线。发现窄矩形通道流量漂移存在4阶段机理,并提出窄矩形自然循环流量漂移起始功率经验关系式。

Abstract: Based on the natural circulation experiment platform, the Flow Excursion of natural circulation in the narrow rectangular channel has been experimentally investigated on the natural circulation experiment platform. When the heating power comes up to a certain range, the natural circulation flow excursion occurs in the system, accompanied by the flow oscillation. The stability of the whole system increases with the increasing of the inlet sub-cooling, the pressure and the channel size. The stability curve of the system is drawn according to the sub-cooling and the phase change. It is discovered that there are 4 stages of flow excursion in the narrow rectangular channel, and the experience formula is proposed for the initial power of natural circulation flow excursion in the narrow rectangular channel.
