Study on the bunching characteristics of underwater plasma sound source

The reflection bunching characteristics analysis of underwater plasma sound source has an important guiding significance on the research and application of underwater directional radiation technology. The reflection rules of different surfaces were analyzed, and the bunching sound field distribution model of underwater plasma sound source based on the Euler equation was established, which was solved by unwind WENO pattern. The intense pulsed acoustic wave bunching and the sound field distribution were analyzed by simulation, and the sound field charts illustrated the reflection bunching characteristics of the sound source. Some related experiments to verify the simulation results were designed. The simulation results are basically identical to the experimental results. It shows that the simulation model is reliable; this information is critical and lays the foundation for the further research on underwater directional radiation technology and the improvement of the source level.
