Effect of Prebreakdown Time on Shock Wave Generation Characteristics of Underwater Plasma Sound Source

Acoustic array bunching is an effective method to realize the directional radiation of underwater plasma sound source (UPSS). The prebreakdown time one decisive factors for performance acoustic bunching. working characteristics and process arc discharge are deeply analyzed. precondition given by analyzing waveforms electrical signals signals. Through experiments based on different aqueous solutions, a feasible scheme in salt water proposed. system parameters, variation under influence charging voltage, conductivity, other parameters was studied. experimental results show that decreases with increase voltage conductivity. At same time, current increases, oscillation decreases, energy injection rate electrode accelerates. research helpful understand mechanism optimize shock wave waveform.
