Upscaling Single-Bubble Sonoluminescence,g the liquid temperature, changing liquid viscosity or surface tension, or, most efficiently, by . the acoustic .. The application of lower frequencies has to be assisted by a simultaneous reduction of the partial inert gas pressure of the dissolved gas (e.g. stronger degassing) to maintain the diffusive stability of the bubbles.

Destructive Action of Cavitation Bubbles Collapsing Near Boundaries,s concerned with the possibility of high-pressure generation by bubble collapse due to interaction of a bubble with other effects such as the shock wave-bubble, bubble-bubble, and bubble-curved boundary interactions.

Shock Focusing in Sonoluminescing Gas Bubbles,y the bubble as it converges and leaves the centre of symmetry. As such a shock propagates towards the centre, upon convergence and subsequent reflection the temperature increases dramatically. Sufficiently high temperatures are predicted to explain the emission of light by the gas.

Shock and Thermal Waves Emanating from a Sonoluminescing Gas Bubble,ure and temperature induced by the rapid bubble collapse, is also treated. The propagation of a solition-like heat wave which is generated by “thermal spike” due to the rapid increase and subsequent decrease in the bubble wall acceleration is also discussed.

We discuss the status of the shock-wave theory of sonoluminescence and alternative explanations. We pose a number of theoretical challenges.

The Shock-Wave Theory of Sonoluminescence,ence’. The reasons for this are not yet fully understood. The most popular explanation at this time is the shock-wave theory of sonoluminescence. This supposes that, because the bubble surface moves inwards supersonically with respect to the air in the bubble during the compressive parts of the acou
