Abstract
The complicated mechanism of gas bubble oscillation in sound field is quite fascinating. One simplified case is a single bubble motivated by specific finite-amplitude sound waves. Based on the modified Keller-Miksis model, a theoretical and numerical investigation of the regular and nonlinear radial oscillations of a gas bubble driven by different given finite-amplitude waves is presented. Some crucial control parameters of the bubble radial oscillations, including radius of gas bubble, acoustic frequency and acoustic pressure, are studied with multiple numerical analysis methods. Parameter regions which are benefit for power spectrum variation of the excitation forces are given, which can provide the foundation for potential engineering applications.
