Abstract:
The present study experimentally investigates shock-induced collapse of bubbles near boundaries of different plasticity and the resulting destructive erosion. Air bubbles held in gelatin are placed close to either a solid wall or a soft clay layer. High pressure impulse generated by a shock tube is employed to trigger bubble collapse. The bubble deformation is visualized by a focused shadowgraph system, and the damage caused to the boundary surface is closely examined as well. The collapse o...     »
