Аннотация:Forced nonlinear pulsations of a gas bubble in liquid when the oscillation frequency of the external pressure of liquid is equal to the natural frequency oscillations of the bubble (resonance) are investigated. A simple formula for the dependence of the oscillation amplitude of the gas bubble on the external pressure amplitude and the thermophysical properties of the gas and liquid viscosity is derived by means of the averaging method. A good agreement of the formula with numerical calculations up to the oscillation amplitude of bubble radius comparable with its equilibrium value is demonstrated.
