- Abstract:
- In an atrocious ocean environment, the lateral propulsion hole could potentially be partly out of water and capture an air cavity. Bubbles would form when the captured air cavity escapes underwater and they may affect the performance of the sonar. The common commercial computational fluid dynamics software CFX was adopted to calculate the ambient flow field around the lateral propulsion hole generated by a moving vessel. The oscillation of the spherical bubble was based on the Rayleigh-Plesset equation and its migration was modeled using the momentum equation. The radiated noise of the oscillating bubble was also studied. The aim is that the results from this paper would provide some insight into corresponding fluid and acoustic study.
