Single-bubble sonoluminescence
Single-bubble sonoluminescence occurs when an acoustically trapped and periodically driven gas bubble collapses so strongly that the energy focusing at collapse leads to light emission. Detailed experiments have demonstrated the unique properties of this system: the spectrum of the emitted light tends to peak in the ultraviolet and depends strongly on the type of gas dissolved in the liquid; sm...

Moving single bubble sonoluminescence has been discovered after searches to find the fluids other than water for observing SBSL. The main property of these fluids is their more viscosity rather than water. In this paper, after introducing the forces which act on sonoluminescing bubble, the moving of the bubble have been simulated. For this purpose, the bubble’s equation of motion is coupled w...
متن کاملThe Role of Surface Tension in Stable Single-Bubble Sonoluminescence
A theory for stable bubble oscillations in high pressure sound fields is presented. It is based on the strong influence of the surface tension on the dynamics of small bubbles and takes into account rectified diffusion and the resonancelike response of small bubbles to very strong acoustic pressure amplitudes. This theory provides an explanation for the existence of small, stably oscillating bu...

We investigate several means of coupling between a sonoluminescing bubble and an applied magnetic field. Recent experiments show a strong quadratic dependence between the forcing pressures required for stable sonoluminescence and magnetic field amplitude. However, all coupling mechanisms calculated here for comparable magnetic fields involve energies no more than one percent the mechanical ener...
متن کاملShape stability of sonoluminescence bubbles: comparison of theory to experiments.
Single bubble sonoluminescence (SBSL) is the brief flash of light emitted from a single, stable, acoustically forced bubble. In experiments, the maximum pressure amplitude with which a bubble may be forced is limited by considerations of spherical stability. The traditional linear stability analysis predicts a threshold for SBSL at a much lower pressure amplitude than experimental observations....
