摘要

为了得到蒸汽在过冷水中浸没射流凝结引起的压力振荡规律

针对不同的过冷水温度和轴向距离对压力振荡特性进行实验研究。实验系统主要包括蒸汽发生器、稳压罐、喷嘴、水箱、仪表、可视化系统和数据采集系统。测量得到了不同轴向位置的压力振荡峰值

通过快速傅里叶变换得到了压力振荡的主频

并分析了过冷水温度和轴向距离对压力振荡特性的影响规律。结果表明:压力振荡峰值总体上随温度升高而增大

但在水温较高时出现下降趋势; 主频随着水温的降低而增大

但不随轴向距离的增大而变化。同时

利用前人提出的公式对本实验条件下的主频进行了计算

计算值与实验值具有相同的变化趋势

且吻合得较好。

Abstract

In order to obtain the pressure oscillation characteristics due to steam jet in water

an experiment was carried out to investigate the pressure oscillation characteristics at various axial positions and different water temperatures. The experimental system mainly consists of a steam generator

a surge tank

a nozzle

a water tank

instrumentations

a camera and a data acquisition system. The pressure oscillation amplitudes were measured and the main frequency was gained by the FFT method. The effects of the water temperature and position on the oscillation characteristic were analyzed. The results show that pressure oscillation amplitudes increased with water temperature

but a decreasing trend was found at high water temperatures. The main frequency decreased as water temperature increased

while the axial position had no effect on the main frequency. In addition

an existing correlation was used to predict the main frequency

and a good agreement was achieved between the predictions and the experiment data.
