TLDR
In this article, the damping constants of resonant bubbles are extended to the off-resonance case and it is shown that thermal damping is important for bubbles driven below resonance, and radiation damping for those above resonance.Abstract:
Results obtained by Devin [J. Acoust. Soc. Amer. 31, 1654–1667 (1959)] for the damping constants of resonant bubbles are extended to the off‐resonance case. Calculated results show for the range of conditions considered that thermal damping is important for bubbles driven below resonance, and radiation damping is important for those above resonance.read more

Predicting the acoustic response of a microbubble population for contrast imaging in medical ultrasound.
Chien Ting Chin,Peter N. Burns +1 more
TL;DR: A modified Trilling equation for single bubble dynamics that has been solved numerically for different conditions is presented and is particularly suited to the study of interaction between a medical ultrasound beam and microbubble contrast agents in aqueous media.

Sound velocity and absorption in a coarsening foam
Nicolás Mujica,Stéphan Fauve +1 more
TL;DR: Experimental measurements of sound velocity and absorption in a commercial shaving foam show that both quantities evolve with time as the foam coarsens increasing its mean bubble radius, and that sound velocity depends on the evolution of the structure of the foam, even in the large wavelength regime.

Effect of dissolved gases in water on acoustic cavitation and bubble growth rate in 0.83 MHz megasonic of interest to wafer cleaning.
TL;DR: It has been shown that change of cavitation intensity in various dissolved gases were verified through cleaning experiments in the single type of cleaning tool such as particle removal and pattern damage based on numerically calculated acoustic bubble growth rates.

Mie scattering used to determine spherical bubble oscillations
TL;DR: In this paper, the boundary value problem for the water-bubble interface is solved by solving the Mie theory, and the inverse transfer function R(I) is obtained by integrating over the photodetector solid angle centered at some constant theta.

Low Frequency Noise from Breaking Waves
TL;DR: In this article, the authors confirm the production of sound by breaking waves at lower frequencies (30 to 500 Hz) and show that the resulting sound can be represented as acoustic monopoles and dipoles.
