DYNAMICS OF A NONSPHERICAL GAS BUBBLE IN LIQUID

Abstract: 

Nonlinear dynamics of a gas bubble in liquid is studied on the basis of quadratic model allowing distor-tions of its shape and spatial translations of the bubble. The liquid compressibility and viscosity are taken into account approximately. Some examples of mutual influence of radial oscillations, the spherical shape distortions, and spatial displacements of an air bubble in water are presented. In the case of periodic varia-tion of the liquid pressure, the area of linear stability of the spherical shape of the bubble as well as the areas with finite-in-time amplitudes of distortions and spatial translations of the bubble is computed. 

Key words: 

gas bubble, nonlinear oscillations, potential flow, spatial translation.
