“…This idea about heat transfer is based on a more careful version of this argument by Kamath et al (1993) and Prosperetti et al (1998). They showed that the temperature T s at the bubble surface is basically the water temperature: Conservation of energy at the bubble interface requires continuity of the heat flux,…”

“…An important aspect of bubble thermodynamics, which has been pointed out by Kamath et al (1993), Yasui (1997b), Colussi and Hoffmann (1999), Moss et al (1999), Szeri (2000, 2001); Toegel, Gompf, et al (2000), Hilgenfeldt et al (2001), andPutterman et al (2001), is the presence of water vapor inside the bubble. Upon bubble expansion, vapor invades the bubble.…”

“…This is quite a difficult task. Over the years, several methods have been proposed that amount to varying ␥ continuously between the isothermal value and the adiabatic value (Plesset and Prosperetti, 1977;Prosperetti et al, 1988;Kamath et al, 1993) depending on the Pé clet number. This approach can yield quantitatively incorrect results, as shown by Prosperetti and Hao (1999), in large part because energy dissipation from thermal processes is neglected.…”

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; small amounts of trace noble gases or other impurities can dramatically change the amount of light emission, which is also affected by small changes in other operating parameters (mainly forcing pressure, dissolved gas concentration, and liquid temperature). This article reviews experimental and theoretical efforts to understand this phenomenon. The currently available information favors a description of sonoluminescence caused by adiabatic heating of the bubble at collapse, leading to partial ionization of the gas inside the bubble and to thermal emission such as bremsstrahlung. After a brief historical review, the authors survey the major areas of research: Section II describes the classical theory of bubble dynamics, as developed by Rayleigh, Plesset, Prosperetti, and others, while Sec. III describes research on the gas dynamics inside the bubble. Shock waves inside the bubble do not seem to play a prominent role in the process. Section IV discusses the hydrodynamic and chemical stability of the bubble. Stable single-bubble sonoluminescence requires that the bubble be shape stable and diffusively stable, and, together with an energy focusing condition, this fixes the parameter space where light emission occurs. Section V describes experiments and models addressing the origin of the light emission. The final section presents an overview of what is known, and outlines some directions for future research.

“…Evaporation and condensation of water molecules at the bubble wall (Kamath et al 1993;Yasui 1997;Storey & Szeri 2000Brenner et al 2002) is included in the model for the bubble dynamics, as experimental results (Toegel et al 2000;Vazquez & Putterman 2000) stress the importance of a decrease in the polytropic exponent induced by water vapour at bubble collapse. A simple Hertz-Knudsen model (Hertz 1882;Knudsen 1950) …”

Based on the theory of F. Gilmore (Gilmore 1952 The growth or collapse of a spherical bubble in a viscous compressible liquid) for radial oscillations of a bubble in a compressible medium, the sound emission of bubbles in water driven by high-amplitude ultrasound is calculated. The model is augmented to include expressions for a variable polytropic exponent, hardcore and water vapour. Radiated acoustic energies are calculated within a quasi-acoustic approximation and also a shock wave model. Isoenergy lines are shown for driving frequencies of 23.5 kHz and 1 MHz. Together with calculations of stability against surface wave oscillations leading to fragmentation, the physically relevant parameter space for the bubble radii is found. Its upper limit is around 6 mm for the lower frequency driving and 1-3 mm for the higher. The radiated acoustic energy of a single bubble driven in the kilohertz range is calculated to be of the order of 100 nJ per driving period; a bubble driven in the megahertz range reaches two orders of magnitude less. The results for the first have applications in sonoluminescence research. Megahertz frequencies are widely used in wafer cleaning, where radiated sound may be implicated as responsible for the damage of nanometre-sized structures.

“…In this work, the internal bubble pressure is calculated using Prosperetti's detailed heat transfer model [16,10], which requires solving partial differential equations for the temperature fields inside and outside the bubble. The method described in our previous work [20] is used for this purpose.…”
