摘要：

Based on high-speed photographic experiments, this study presents a detailed qualitative and quantitative analysis of the dynamics of a single cavitation bubble near the boundary of a rigid wall in asymmetric settings. The main findings are reported as follows: (1) The non-sphericity of the bubble interface decreases with increasing spacing between the bubble and the boundary, and the asymmetry of the bubble becomes more significant with increasing asymmetry angle. (2) The motion mode of the bubble cluster in the second oscillation cycle can be divided into two typical modes depending on the direction of movement. (3) The angle between the oblique jet pointing towards the upper wall surface and the horizontal direction in the second oscillation cycle decreases as the dimensionless spacing decreases.
