Enhancement of Shock Wave From Underwater Electrical Wire-Array Explosion at a Fixed Energy by Changing Wire Connection

An energy-efficient method is developed to generate shock wave from underwater electrical wire-array explosion. By changing wire connection of cylindrical wire-array, parallel is found usually not the suitable connection of wire-array to generate shock wave at a fixed energy. The suitable connection of wire-array is determined by initial energy. At a given initial energy, resistance matching between load and external resistance is an important factor to generate shock wave, and the corresponding discharge current is critically damped discharge.
