In order to clarify the phenomena of bubble growth and coalescence, we studied the growth and release behavior of bubbles formed at a nozzle tip, the coalascence of two bubbles formed at a dual-nozzle tip, the coalescene of many bubbles in a liquid, and the flow behavior of bubble groups. We also studied the conditions at the onset of bubble coalescence in terms of a hypothesis, derived from the earlier observation results, that bubble coalescence is strongly affected by the degree of swing in the paths of the bubbles.
