Phase diagrams for sonoluminescing bubbles
Sound driven gas bubbles in water can emit light pulses. This phenomenon is called sonoluminescence ~SL!. Two different phases of single bubble SL have been proposed: diffusively stable and diffusively unstable SL. We present phase diagrams in the gas concentration versus forcing pressure state space and also in the ambient radius versus gas concentration and versus forcing pressure state space...
متن کاملViscosity destabilizes sonoluminescing bubbles.
In single-bubble sonoluminescence (SBSL) microbubbles are trapped in a standing sound wave, typically in water or water-glycerol mixtures. However, in viscous liquids such as glycol, methylformamide, or sulphuric acid it is not possible to trap the bubble in a stable position. This is very peculiar as larger viscosity normally stabilizes the dynamics. Suslick and co-workers call this new myster...
متن کاملInert gas accumulation in sonoluminescing bubbles
In this paper we elaborate on the idea @Lohse et al., Phys. Rev. Lett. 78, 1359–1362 ~1997!# that ~single! sonoluminescing air bubbles rectify argon. The reason for the rectification is that nitrogen and oxygen dissociate and their reaction products dissolve in water. We give further experimental and theoretical evidence and extend the theory to other gas mixtures. We show that in the absence o...
متن کاملAnalysis of Rayleigh–Plesset dynamics for sonoluminescing bubbles
Recent work on single-bubble sonoluminescence (SBSL) has shown that many features of this phenomenon, especially the dependence of SBSL intensity and stability on experimental parameters, can be explained within a hydrodynamic approach. More specifically, many important properties can be derived from an analysis of bubble wall dynamics. This dynamics is conveniently described by the Rayleigh–Pl...
متن کاملSqueezing alcohols into sonoluminescing bubbles: the universal role of surfactants
We conduct an experimental study of the dependence of single bubble sonoluminescence intensity on the concentration of various alcohols. The light intensity is reduced by one-half at a molar fraction of ethanol of approximately 2.5x10(-5); butanol achieves the same reduction at a concentration 10 times smaller. We account for the results by a theoretical model in which the alcohols are assumed ...
