Abstract
<p>This paper reports on the visualization results of the phenomena of interaction of underwater shock wave induced by the electrical pulsed discharge with microbubbles attached to the solid wall and the behavior of bubbles collapse caused by the shock wave loading. The effect of microbubble diameter on the behavior was investigated. The time histories of microbubble diameter which was constricted by the underwater shock wave loading was also researched by analyzing the visualized images. The images and analysis results quantitatively clarified that the time of microbubble collapse induced by the shock wave interaction was increased as the increased of that diameter.</p>
