Gas temperatures in bubble oscillations

Sonolumineseenec effects are critically dependent on the temperature field of the gas contained in oscillating bubbles. Polytropic models of the gas pressure-volume relationship are totally inadequate for an accurate determination of the temperature. A better model based on the conservation equations of continuum mechanics is described and its predictions illustrated with a number of examples. The influence of the computed temperature field on a model dissociation reaction is illustrated. [Work supported by NSF.]
