• This paper presents experimental studies on vibration of an axisymmetric body in a cavitating leakage flow. The experimental passage is a narrow annular parallel passage. The effects on the characteristics of vibration and the flow pattern in the passage were evaluated by changing the width of the passage, the downstream pressure and other conditions. From the experimental results, the following conclusions were obtained. When the narrow passage becomes choked and the cavitation bubbles are concentrated around the wake, a divergent passage is formed by the columniform bubbles, and self-excited vibration due to the negative damping occurs in the system. Under such conditions, the self-excited vibration becomes intense when the cavitation number is about 0.2.
