微腔体内微泡的声辐射力
Acoustic Radiation Force of Microbubbles Within Microcavities
摘要
Abstract
The trapping mechanism of microbubbles is analyzed based on microbubble acoustic radiation force theory and numerical simulation,and the acoustic radiation force of microbubbles in microcavities is studied.The theoretical analysis showed that when the driving frequency of the sound field is lower than the resonant frequency of the microbubble,the force direction of the microbubble points to the maximum value of the sound field.When the driving frequency of the sound field is higher than the resonant fre-quency of the microbubble,the force direction of the microbubble points to the minimum value of the sound field.Combined with finite element simulation of the quartz cavity,it is verified that the resonance properties exhibited by microbubbles of different sizes in the same acoustic field are different.Smaller microbubbles move towards the acoustic field minimum under the action of standing waves,while larger microbubbles move in the opposite direction.关键词
