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, respectively. 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 small ambient radius is stronger than that of bubbles with large ambient radius under the same driving acoustic pressure. This effect increases with an decrease in the distance between two bubbles. When compared to single-bubble sonoluminescence, the interaction between two bubbles leads to the generation of different spectral characteristics.

双泡声致发光光发射的计算与分析

我们对水中两个声致发光气泡的光发射进行了计算模拟。我们的模拟分别通过数值求解双气泡系统的脉冲方程和气体动力学方程，包括两个气泡的半径、辐射声压和光发射光谱。仿真结果表明，由于来自另一个脉冲气泡的辐射声压，双气泡系统中每个气泡的运动受到抑制。在相同的驱动声压下，小环境半径气泡的抑制振荡强于大环境半径气泡。这种效果随着两个气泡之间距离的减小而增加。与单泡声致发光相比，
