Method of Direct Numerical Simulation of Intermodal Energy Transfer by Oscillations of Bubble

摘要

A technique is proposed for computer modeling of the energy exchange between the radial and deformation modes of oscillations of a gas bubble in a liquid. Calculations were performed in the case of a resonance of 2 : 1 between these modes using the proposed method and in the weakly nonlinear approximation within the framework of the analytical approach. Qualitative agreement of surface mode configurations calculated by the these approaches is obtained.
