Abstract

Deformation and sound emission of bubble in water are simple phenomena, but contain important physics. In this study, at first, deformation behavior and emitted sound from a bubble were measured at detaching from a nozzle installed in water with varying the diameter of nozzles. After that, CFD simulation using VOF method was used to reproduce these data. As a result, by setting the simulation conditions appropriately, not only deformation behavior but also sound pressure level were agreed well with experimental data and knowledge on emitted sound and flow characteristics around bubble was obtained. Especially, simulation models and conditions were discussed in detail.
