The efficiency of modeling of the axisymmetric dynamics of a gas bubble near a curved rigid wall by the boundary element method using the fundamental solution of the Laplace equation for an unbounded domain is numerically studied. For this purpose, t

A numerical study of the dynamics of a gas bubble in water near a plane rigid wall under ultrasound excitation has been performed. The bubble dynamics is excited at the natural frequency of the radial oscillations of the bubble in the absence of the

Influence of initial non-sphericity of a gas bubble on its dynamics at various distances from a plane rigid wall under harmonically varying liquid pressure is investigated. The initial shape of the bubble is taken to be a spheroid with the axis of sy

Expansion, collapse and impact of a gas bubble onto a rigid wall are numerically studied. The bubble is adjacent to the wall, it is initially spherical, at the equilibrium state. Its dynamics results from harmonic variation of the surrounding liquid

The dynamics of a bubble near a local axisymmetric convexity or concavity, cosine-like in the axial section, on a plane rigid wall is studied under conditions of formation of a cumulative liquid jet directed to the wall. The study is performed by the

A numerical technique based on the application of the boundary element method is proposed for studying the axially symmetric dynamics of a bubble in a liquid near a solid wall. It is assumed that the liquid is ideally incompressible and its flow is p

Dynamics of a gas bubble in a liquid near a solid wall is studied. The influence of the initial spheroidal disturbances of the bubble shape and the distance to the wall on the dynamics of the bubble–liquid system is analyzed. The pressure in the bu
