Numerical Integration Methods in Gas Bubble Dynamics
(The Journal of the Acoustical Society of America, 1989-04)
A recent detailed formulation of the dynamics of a gas bubble requires the numerical integration of a nonlinear heat equation in the bubble. In this article, a variety of numerical methods for this purpose are studied. The ...
Rayleigh-Taylor Instability for Adiabatically Stratified Fluids
(The Physics of Fluids, 1989-11)
A linear analysis of the effects of compressibility on the stability of two superposed isentropic fluids is presented. The results of the analysis, which differ from those available in the literature for other unperturbed ...
Bubble-Related Ambient Noise in the Ocean
(The Journal of the Acoustical Society of America, 1988-09)
An analysis is presented of the mechanisms by which bubbles can generate ambient noise in the ocean and the resulting noise levels are estimated. Bubbles can be extremely efficient amplifiers of water turbulence noise up ...
The oscillations of a small floating bubble
(The Physics of Fluids, 1989-02)
A simple model of a small bubble floating at the surface of a liquid before bursting is considered. The oscillations of this system are studied by means of a Lagrangian method. It is found that two fundamentally different ...
Reply to Comments on “General Analysis of the Stability of Superposed Fluids”
(The Physics of Fluids, 1982-05)
Previous results by Plesset and Hsieh on the effects of compressibility for Rayleigh–Taylor instability are shown to be valid, and an alternative brief deduction is given.
The stability of an evaporating liquid surface
(The Physics of Fluids, 1984-07)
A linearized stability analysis is carried out for an evaporating liquid surface with a view of understanding some observations with highly superheated liquids. The analytical results of this study depend on the unperturbed ...
Linear pressure waves in bubbly liquids: Comparison between theory and experiments
(The Journal of the Acoustical Society of America, 1989-02)
Recent work has rendered possible the formulation of a rigorous model for the propagation of pressure waves in bubbly liquids. The derivation of this model is reviewed heuristically, and the predictions for the small?amplitude ...
The Motion of a Charge Particle in a Uniform Magnetic Field
(Il Nuovo Cimento, 1980-06)
We study the motion of a classical (nonquantal) charged particle in a uniform magnetic field by means of i) the Abraham-Lorentz equation, ii) the Dirac relativistic equation and iii) the Caldirola nonrelativistic, ...
The Underwater Noise of Rain
(Journal of Geophysical Research: Oceans, 3/15/1989)
Numerous data on the spectra of underwater noise due to natural as well as artificial rain show a prominent and characteristic peak at a frequency around 14 kHz. It is argued that this acoustic emission is due to bubbles ...
