| To study the acoustic efficiency problem of an underwater plasma sound source discharge system, a complete set of models for computation of the acoustic efficency of the system were established based on the analyses of the microcosmic mechanisms of corona discharge and spark discharge of underwater plasma, and the investigation of the energy transformation process of each part of the system. The experimental system for underwater pulsed discharge was proposed. The acoustic efficiency of underwater pulsed corona discharge and that of underwater pulsed spark discharge were compared and analyzed by the experiments with the self established underwater plasma sound source experiment system. The experiments discovered that the acoustic efficiency of underwater spark discharge was evidently high in this system. On the basis of this, a series of performance experiments were carried out, and the influences of the key components of the underwater plasma discharge system on the acoustic efficiency were presented. The acoustic efficiency analysis can be used to evaluate the design of a pulsed discharge system. |
