On the Motion of Two Superposed Viscous Fluids
(The Physics of Fluids, 1981-07)
The initial?value problem associated with the small?amplitude waves on the interface between two superposed viscous fluids is studied in the stable and in the unstable case (Rayleigh–Taylor instability). The results are ...
Nonlinear bubble dynamics
(The Journal of the Acoustical Society of America, 1988-02)
The standard approach to the analysis of the pulsations of a driven gas bubble is to assume that the pressure within the bubble follows a polytropic relation of the form p=p0(R0/R)3?, where p is the pressure within the ...
The hydrodynamic interaction of two slowly evaporating spheres
(The Physics of Fluids, 1989-10)
The Stokes flow induced by the slow evaporation or condensation of two spheres is studied. The phase?change velocity is prescribed and uniform over the surfaces of the spheres. Exact expressions are obtained for the ...
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 ...
