ABSTRACT
An experimental study of the extinction threshold single bubble sonoluminescence in an air-water system is presented. Different runs from 5% to 100% air concentrations were performed at room pressure and temperature. The intensity (SL) time collapse (tc) with respect driving measured while acoustic was linearly increased onset SL until extinction. data compared theoretical predictions for shape position instability thresholds. It found that determined by different mechanisms depending on concentration. For greater than ∼30%–40% saturation, parametric limits maximum value R0 can be reached. On other hand, lower concentrations, appears as a limitation collapse. Two emerge this range, i.e., Bjerknes force Rayleigh–Taylor instability. emission produces backreaction itself. This effect occurs both essential correct prediction case low dissolved
