摘要

A modified Keller–Miksis equation is presented for describing the motion of a gas bubble covered by an anisotropic shell in liquid, taking into account its radial oscillations. The influence of the bubble shell anisotropy on its radial dynamics in an external acoustic field is analyzed. A mathematical model of acoustic wave propagation in liquid with gas bubbles covered by an anisotropic shell is constructed and an analytical expression for the resonant frequency of bubble oscillations is found. The influence of bubble shell anisotropy on the dynamics of an acoustic wave in liquid is investigated.
