Dynamics of the Bubble near a Triangular Prism Array
Download citation file:
The behaviors of cavitation bubbles are significantly influenced by the nearby objects. In practice, the bubble usually oscillates and collapses near complex structures. In this study, the dynamics of a laser-induced single bubble near a triangular prism array are investigated experimentally. The behaviors of the bubble, such as the collapse, the resound, and the jet formation, are revealed, which are strongly influenced by several parameters, e.g., the relative position of the bubble and the prisms, the size of the bubble and the distance between the bubble and the array.
