Explaining Unwanted Radial Oscillations in Single-Bubble Sonoluminescence

This study presents a theoretical model to explain the bubble oscillation phenomenon that occurs after each flash in single-bubble sonoluminescence (SBSL). Our model reveals that these fluctuations are caused by the pressure effect of electrons produced during the flash, which interact with the surrounding fluid and cause bubble formation. The authors use the Monte Carlo method to calculate the number of released electrons and demonstrate that the amplitude and frequency of these oscillations can be reduced by manipulating the electron density and energy distribution. By controlling the released electrons, we show that it is possible to reduce the number of unwanted oscillations and increase the number of flashes that can be performed in a given time interval. The results provide new insights into the mechanism of SBSL and have implications for its application in various fields. Furthermore, our findings offer a method for reducing these oscillations, which limit the number of flashes that can be produced in a time interval, allowing for more efficient and reliable operation. The results from our theory are in good agreement with experimental results, validating our understanding of this phenomenon.
