Multipole resonances of an isolated gas bubble in water excited by sound waves

  • Based on the theory of the multipole resonances in sound scattering from an isolated gas bubble in water,the mechanisms of the scattering and absorption of sound waves by a gas bubble in water are analyzed,with the effects of the thermal conduction in the gas,the viscosity and surface tension of water considered.It is shown that the scattering and absorption of sound waves by a gas bubble reduce quickly with the series of resonances increasing;at resonancesl the thermal conduction in the gas is decisive in the dissipative effects of a gas bubble;compared with the case in which the effects of the thermal conduction in the gas;the viscosity and surface tension of water are ignored;the resonance frequnces of a gas bubble are changed.
