Dynamics of an Acoustically Excited Gas Cavity Attached to a Rigid Surface

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 pressure. The impulse action of the bubble on the...
