Bjerknes力对微气泡运动特性的影响
The effect of Bjerknes force on motive behaviors of micro-bubble
摘要
Abstract
Using the bubble control equation, the motive behaviors of micro-bubble in acoustic standing wave field are numerically simulated with regarding water as a working medium. The effects of Bjerknes forces on bubble trajectory are investigated. Our results show that the coefficient of Bjerknes forces varies several orders of magnitude with different acoustic pressure values or different locations. During micro-bubble moving to the acoustic pressure antinode area, primary Bjerknes force increases at first and then decreases, but secondary Bjerknes force increases continuously. The interaction of them forms a ring around acoustic axis, and the greater acoustic pressure value will induce the greater ring.关键词
