| The paper considers the dynamics of a gas cavity in an ideal compressible fluid as a result of the pulsed input of energy into it. The process of generating a spherical pressure wave in fluid generated by gas cavity pulsations is investigated. An algorithm for calculating the fluctuations of the cavity in nonlinear statement on a fixed Eulerian grid is proposed. A comparative analysis of the bubble dynamics in linear and nonlinear formulation is presented. |
