J0203-2-5 Observation of bubble deformation process in a capsule by underwater pressure wave

Abstract

This paper describes the fundamental investigations for developing new technology using shock waves and bubbles, such as drug delivery systems (DDS). To understand the fundamental phenomena, deformation process of a bubble in a microcapsule is observed by pressure waves to analyze the behavior of the bubble collapsing in the microcapsule. It is found that by selecting the proper parameters, there are possibilities to make the large deformation of bubble to disintegrate.
