ABSTRACT

A set of solutions of the Navier-Stokes equation for the gas inside a spherical bubble with heat transfer through the bubble wall permits to predict correctly characteristics of sonoluminescing bubble in aqueous solutions of sulfuric acid. Calculation results of the minimum velocity of bubble wall, the peak temperature and pressure, and the flash width of the sonoluminescence (SL) are in excellent agreement with the observed ones. Further the calculated bubble radius-time curve displays alternating pattern of bubble motion as observed in experiment. The origin of sonoluminescence from gas bubble in sulfuric acid turns out to be blackbody emission with finite absorption.
