Research Abstract

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.
