Acoustic vibrational resonance in a Rayleigh-Plesset bubble oscillator

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.
