Abstract

A fine wire was exploded in water by rapid release of energy stored in a condenser bank to generate a shock pressure in water. In order to clarify the mechanism of shock-pressure generation, the exploding process of the wire and the motion of a cavity produced by the wire-explosion were observed by a high speed streak camera and a framing camera respectively. Electrical quantities of the discharge and the shock pressure were also measured simultaneously with the optical observation. It was found that shock pressure was emitted from the wire when the wire was vaporized. The cavity formed in water by the wire-explosion collapsed spherically after maximum expansion and reversely expanded after reaching minimum radius. Shock pressure was generated at the start of this expansion.
