Abstract :
The double-bubble model is formed in the spherical coordinates, which is based on the distribution of bubbles in the ship wake. The multi-bubble models are created and the finite element structure models of the multi-bubble are formed and studied by then. A sound source is located in the field point models of the multi-bubble, and the active acoustic characteristic of the models are obtained by the finite element analysis. The experiment of multi-bubble in the ship wake is simulated, which could be used to direct the practical experiment and the application of the theory.
