PHYSICS OF MICROBUBBLES,
Abstract
A bubble model is developed in which a compressed wall of particles supports a portio of the hydrostatic pressure, neutralizing the out-diffusion of gas and the buoyancy to produce stabilization. Other suggested effects are an increase of bubble resonant frequency, a reduction of damping, and a critical size marking a transition between a radius controlled cavitation threshold to one primary controlled by the dissolved gas pressure. The implications to cavitation and sound propagation are explored. Scattered experimental evidence suggests that microbubble concentrations occasionally exceed critical limits. (Author)
