摘要
单泡声致发光现象中,气泡动力学特性的研究是十分重要的。文章由简单的振子模型及能量守恒定律,导出了不可压缩、弱粘滞流体中纯径向振动气泡的Rayleigh-Plesset方程,利用龙格-库塔法计算了不同驱动声压下的R(t)曲线,并对崩溃相气泡的聚能效应做了讨论。
Study of dynamic behaviors of gas bubble in single bubble sonoluminescence is very important. Based on the vibrator model and the law of energy conservation, the Rayleigh-Plesset equation is derived for a bubble radially vibrating in an incompressible and weakly viscous liquid. Curves of R(t)at different driving acoustic pressures are calculated numerically with the Ronge-Kuta method. The effect of energy concentration of bubbles in the collapsing phase is discussed.
