A Bubble Distribution Model in Remote Ship Wake Construction and Simulation
The characteristics of ship wake and a bubbles distribution model in ship wake were researched. According to the features of a vessel, a bubble distribution model in the vessel wake were simulated and then applied to predict sound propagation attenuation in ship wakes. Simultaneously, the vessels wake was measured on a lake at range of frequency from 4kHz to 20kHz, which were analyzed to explore the performance of the presented model. The comparison results show that the void fraction of bubbles in the vessels wake reach1.1410-6 , and the difference between the predicted attenuation and the measurements of sound propagation attenuation in the wake are less than 5dB/km, which agree well with experiment results. Thus, the bubble distribution model of ship wake can be used to research the acoustical characteristics in ship wake to overcome the data incompleteness.
