碩士 / 國立成功大學 / 水利及海洋工程學系 / 86 / The purpose of the present study is to study the trajectories
of underwater explosion bubbles. The study of bubble motions
proceeds by assuming irrotational flow in an incompressible
and inviscid fluid. The trajectories ofbubbles were determined
for two different cases, one of which the bubble wasgenerated
in a free field; while in the former case, our numerical
resultsshowed that the bubble moves upwards slowly in the course
of bubble expansion;and it moves upwards faster in the course
of contraction, expecially at itsminimum radius. When a plane
solid boundary existed beneath the bubble, thebubble will move
towards the boundary before it moves upwards.
