A computational study of bubble-structure interaction

The complex interaction bent een underwater explosion bubbles and nearby structures is studied using two-fluid computational fluid dynamics. Gravitational effects on bubble jetting are significantly different between jet-up and jet-down orientations. This paper presents computational results of underwater explosion hubble dynamics near a disk anti a sphere. The results show that the bubble jetting and collapse phenomena and the consequent pressure lending are affected br the structure's shape, the orientation of the bubble to the structure, and the bubble depth. A unifying notion emerges connecting jet strength at impact to bubble curvature at the time of jet formation.
