A gas bubble under the influence of an ultrasonic field so strong to destroy any material due to high pressures and temperatures reached during the collapse is the topic of the present paper. In the current work, simulations have been performed to describe the radial dynamics of a gas (argon) bubble being strongly forced to periodic oscillation in a highly viscous liquid like aqueous sulfuric acid solution. The basic equations for nonlinear bubble oscillation in a sound field are given, together with a survey of some important existing studies. The hydrodynamics forces acting on the bubble are taken into account to consider the bubble dynamics under the action of a sound wave. The theory permits one to predict correctly the bubble radius–time behavior and the characteristics of a microsize bubble in sulfuric acid solutions, such as the peak temperature and pressure fields generated at this occasion.
