摘要
在自然循环水回路上进行了两相流密度波不稳定性的实验研究，得到了不同工况下的实时脉动曲线。分析了系统压力、质量流密度、进口欠热度对系统稳定边界的影响。得出了用无量纲量相变数Ｎｐｃｈ、欠热度数Ｎｓｕｂ、弗劳德数Ｆｒ表示的系统稳定边界图及稳定性判别准则式。
This paper describes the experimental study of two phase density wave oscillation in natural circulation loop. The oscillation curves under different conditions are obtained. In the experiment, the effects of various system parameters such as system pressure, inlet subcooling, and mass flow rate etc. on flow instability are examined; and the marginal stability boundary of the system is determined by non dimensional parameters: the subcooling number N sub and the phase change number N pch .And a stability criterion including the Froude number is developed also.
