Study on flow-induced acoustic vibration of main steam pipe for power uprate

为了防止核电站主蒸汽管道的损坏，对腔体的流致声共振进行了实验研究。本研究的重点是定性和定量地阐明高雷诺数空腔流动的特性。使用缓冲罐30秒实现了高速流动。利用高速PIV技术对流动脉动进行了定量研究。利用实验结果对声共振的机理进行了研究。

Flow-induced acoustic resonance of cavity had been experimentally investigated in order to prevent the damage of Nuclear Power Plant at the main steam line. The focus of the present investigation is on the clarification of characteristics of cavity flow with high Reynolds number quantitatively and qualitatively. The high-speed flow had been realized using the buffer tank for 30 seconds. The flow fluctuation had been quantitatively clarified using High-speed PIV technique. The mechanism of the acoustic resonance had been investigated using the experimental results.
