Numerical simulation of underwater plasma intense acoustic focusing sound field

Underwater plasma intense acoustic focusing sound field modeling and simulation computation has the important guiding significance regarding to the design and evaluation of underwater plasma discharge system. In this paper, we adopts Euler equation as underwater plasma intense acoustic focusing sound filed distribution model, and solve the equation by unwind WENO scheme. The intense pulsed acoustic wave propagation and the focusing sound field distribution is analyzed by simulation, and further verified by some related experiments. Comparing the simulation and the experiment result, a good matching can be found. It shows that the simulation model is reliability and effectiveness in the studying of underwater focusing shockwave sound field.
