The article describes different patterns of bubble deformation during the cavitation bubble collapse close to a solid wall for different bubble-wall distances. The bubble is generated by energy discharge in water. The collapse patterns are investigated using high-speed photography. The magnitude of the bubble-wall interaction is measured using the PVDF film. The shock wave pressure in the far field is measured using the PVDF hydrophone.
