Research Institute of Mechanics and Machinery of Kazan Scientific Center of the Russian Academy of Sciences

Abstract: A modified Keller–Miksis equation, taking into account radial oscillations of a gas bubble covered by an anisotropic shell and located in the carrier liquid is presented. Numerical calcu- lations are performed. The influence of the shell anisotropy on the radial oscillations of a gas bubble in an external acoustic field is analyzed. In a particular case, a comparison of the theory with available experimental data is given.

Key words: acoustic field, gas bubble, anisotropic shell.
