THEORETICAL-STUDIES OF SONOLUMINESCENCE RADIATION - RADIATIVE-TRANSFER AND PARAMETRIC DEPENDENCE

We present results for sonoluminescent (SL) radiation from a strongly modulated air bubble in water. The SL pulse is due to high temperatures in the bubble produced by the collapse of a shock wave. The dependence of SL radiation on acoustic pressure and initial bubble size is discussed, as well as the inclusion of various mechanical energy loss mechanisms. We find that inclusion of loss terms, especially due to radiation, is necessary in order to understand the bubble dynamics, the resulting SL pulse, and some recent experiments.
