The Translations of Avitation Bubbles in the Acoustic Field
摘要
Abstract
By analyzing the pressure near cavitation bubbles, a set of ordinary differential equations for the pulsation and translation of N cavitation bubbles on a one-dimensional chain is obtained. The effects of ambient radius and initial distance on the translations of cavitation bubbles are discussed. The results show that when the ambient radii of the bubbles at both ends and the initial distance from the middle bubble are all the same, the magnitude of the interaction force is equal, that when the direction is opposite, they then move symmetrically towards the middle bubble, and that when the force on the middle bubble is zero, then the middle bubble hardly moves. The smaller the initial distance, the greater the interaction force between them. When the ambient radii of bubbles are different, the strength of the interaction force between bubbles depends on the initial distance. These findings have direct significance for understanding the cavitation structure in the sound field.关键词
