Frontiers in Energy 2009, Volume 3, Issue 3,   Pages 307-312 doi: 10.1007/s11708-009-0028-7

Abstract: A model was set up to describe the behavior of the bubble in a visual experimental system in which ahigh-speed camera rose instantaneously with the movement of the bubble.A series of trajectory videos about the bubble were recorded by a computer linked to the camera.The trajectory, volume changes and rate of mass transfer of the bubble were obtained by the CIPT.With the volume decreasing, the disturbed behavior of the bubble becomes tempered.
