摘要

We perform a computational simulation of light emissions from two sonoluminescent bubbles in water.Our simulation includes the radii of two bubbles,radiation acoustic pressures,and light emission spectra by numerically solving the pulsing equations of a two-bubble system and the equations of gas dynamics.The simulation results demonstrate that the motion of each bubble in the two-bubble system is restrained because of the radiation acoustic pressures from the other pulsing bubble.The restrained oscillation of a bubble with a small ambient radius is stronger than that of a bubble with a large ambient radius under the same driving acoustic pressure.This effect increases when the distance between the two bubbles decreases.When compared to single-bubble sonoluminescence,the interaction between two bubbles leads to generation of different spectral characteristics.
