| 摘 要： | 本文建立了超声激励下微管内微泡的有限元数值分析方法。计算结果表明微管内微泡的振动受到一定程度的限制。微泡的有效半径膨胀率和振动频率随着微管半径的减小而减小。同时,微管内微泡的形变为非球形,且程度随着入射声压幅值的增大而变得明显。因此,微管内的微泡动力学行为不同于无限大液体中。

| Abstract: | The dynamic behaviour of a microbubble confined within a rigid micro-tube was studied using finite element method.The results indicated that the microbubble oscillation was limited when constrained within the micro-tube.Both the expansion ratio of its effective radius and natural frequency decreased with the decrease of the tube radius.Meanwhile,the deformation of the microbubble was non-spherical and became more significant when the ultrasound pressure amplitude increased.The dynamic behaviour in micro-tub... |
