| 1 | Analysis on the factors that influence bubble coalescence in an acoustic field显示文摘The coalescence time between two contacting bubbles was measured experimentally in different acoustic pressures and frequencies using an imaging system with a high-speed video camera,and taken an analysis to the influence of the secondary Bjerknes force and maximum oscillation velocity on the coalescence time of two contacting bubbles in this paper.It showed that under the action of different acoustic pressures and frequencies,the coalescence time increases with secondary force and maximum oscillation velocity.The analysis and comparison of the secondary Bjerknes force and maximum oscillation velocity for the effect of bubble coalescence time showed that the secondary Bjerknes force is the critical factor to influence the bubble coalescence. | JIAO Junjie HE Yong PAN Xuchao HE Yuan WANG Chuanting | 2016 | Chinese Journal of Acoustics2016，35，1： | 3 |
