چکیده
The phenomenon of vibrational resonance (VR) has been investigated in a Rayleigh-Plesset oscillator for gas bubble oscillating an incompressible liquid while driven by dual-frequency force consisting high-frequency, amplitude-modulated, weak, acoustic waves. complex equation the model was expressed as dynamics classical particle potential well Liénard type, thus allowing us to use both numerical and analytic approaches investigate occurrence VR. We provide clear evidence that acoustically-driven oscillates time-dependent single or double-well whose properties are determined density its surface tension. show theoretically numerically that, besides VR effect facilitated variation parameters on which high-frequency depends, amplitude modulation, contribute significantly In addition, we discuss observation multiple resonances their origin case, connection low frequency, field.

The inertial cavitation of bubble clouds has been considered to be the hidden crucial mechanism for recent new therapeutic ultrasound applications such as Histotripsy and the ultrasound drug delivery. Although many models are already put forward to simulate the cavitation process, due to the inaccessible experimental validation, which model works closest to the real world situation is not well ...

The results of analytical study of vibrational resonance (VR) occurring in overdamped bistable system driven by two periodic signals with very different frequencies are presented. Approximate solutions for responses at the low-frequency as a function of the amplitude, and the frequency of the additional high frequency modulation which describe well the main features of vibrational resonance are...
متن کاملComparison of the Rayleigh–Plesset and Gilmore Equations and Additional Aspects for the Modelling of Seismic Airgun Bubble Dynamics
Seismic airguns are commonly used in geophysical exploration. More recently, they are also being used as an alternative to underwater explosions for the shock testing of defence vessels. The study of the dynamics of the bubble produced by a seismic airgun is beneficial in understanding the resultant pressure field and shockwave. The Rayleigh–Plesset and Gilmore equations for modelling spherical...
متن کاملAnalysis of Rayleigh–Plesset dynamics for sonoluminescing bubbles
Recent work on single-bubble sonoluminescence (SBSL) has shown that many features of this phenomenon, especially the dependence of SBSL intensity and stability on experimental parameters, can be explained within a hydrodynamic approach. More specifically, many important properties can be derived from an analysis of bubble wall dynamics. This dynamics is conveniently described by the Rayleigh–Pl...
