We present theoretical calculations of an argon bubble in a liquid solution of 85%wt sulfuric acid and 15%wt water in single-bubble sonoluminescence. We used a model without free parameters to be adjusted. We predict from first principles the region in parameter space for stable bubble evolution, the temporal evolution of the bubble radius, the maximum temperature, pressures, and the light spectra due to thermal emissions. We also used a partial differential equation based model (hydrocode) to compute the temperature and pressure evolutions at the center of the bubble during maximum compression. We found the behavior of this liquid mixture to be very different from water in several aspects. Most of the models in sonoluminescence were compared with water experimental results.
我们给出了在单泡声致发光中,85%(重量)硫酸和15%(重量)水的液体溶液中氩气泡的理论计算结果。我们使用了一个无需调整自由参数的模型。我们从第一性原理预测了参数空间中气泡稳定演化的区域、气泡半径的时间演化、最高温度、压力以及热发射产生的光谱。我们还使用了基于偏微分方程的模型(流体力学程序)来计算气泡在最大压缩期间中心处的温度和压力演化。我们发现这种液体混合物在几个方面的行为与水有很大不同。声致发光中的大多数模型都是与水的实验结果进行比较的。
