    Abstract
  • The acoustic characteristics of ship wake depend on that of the bubbles in the wake. A double bubbles model is established in this study according to the distributions of radius and number density of the bubbles in ship wake. Moreover, multi-bubble models are built by using the finite element method and the corresponding software. The node displacement and pressure distribution of the multi-bubble models in the condition of periodically varying load are gained and analyzed. A sound source is introduced into the acoustic field analysis to simulate the environment of the bubbles in ship wake. Experiment is conducted in laboratory to obtained active acoustic characteristic of ship wake through comprehensive analysis.
