Computations of three‐dimensional Rayleigh–Taylor instability
(The American Institute of Physics, 1990-05)
The fully three‐dimensional deformation of an interface between two fluids resulting from a Rayleigh–Taylor instability is studied numerically in the limit of weak stratification. The Navier–Stokes equations are solved by ...
Water diffusion profile measurements in epoxy using neutron radiography
(Elsevier, 1994-12-30)
The diffusion characteristics of water in polymer materials have been studied for a few decades. Several methods have been developed to provide water diffusion characteristics as a function of time, temperature, pressure, ...
Orientation-dependent phase equilibria in in_1-x Ga_x As: A model including surface energies
(Elsevier, 1985)
Orientation-dependent growth phenomena have been observed for liquid-phase epitaxial In1-xGaxAs and other ternary and quaternary III-V semiconductors. The data cannot be explained by existing regular solution phase equilibria ...
Theory of Oscillation of a Viscoelastic Medium between Parallel Planes
(The American Institute of Physics, 1959-12)
A theoretical description of sinusoidal oscillation of an incompressible viscoelastic medium between fixed infinite parallel planes is presented. The mechanical properties of the viscoelastic medium under sinusoidal shear ...
Conservation laws and symmetries of generalized sine-Gordon equations
(Springer-Verlag, 1981-06)
We study some systems of non-linear PDE's (Eqs. 1.1 below) which can be regarded either as generalizations of the sine-Gordon equation or as two-dimensional versions of the Toda lattice equations. We show that these systems ...
Ionization and Scattering for Short-Lived Potentials
(Kluwer Academic Publishers; Springer Science+Business Media, 1999-06)
We consider perturbations of a model quantum system consisting of a single bound state and continuum radiation modes. In many problems involving the interaction of matter and radiation, one is interested in the effect of ...
Modification of Stokes' law for a heated sphere in liquid helium II
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1971-07)
It is shown that the counterflow which occurs at low heat inputs in liquid helium below the λ point modifies the wake behind a steadily moving sphere. The result is valid for a low Reynolds number and limits on the range ...
Structure of 11Li in the cluster-orbital shell model for the 9Li+n +n system
(Elsevier, 1990-04)
The properties of 11Li are studied in detail in the cluster-orbital shell model assuming the structure of 9Li+n+n. The interactions acting between the constituent particles are carefully determined consistently with available ...
An Adaptively Refined Cartesian Mesh Solver for the Euler Equations
(Elsevier, 1993-01)
A method for adaptive refinement of a Cartesian mesh for the solution of the steady Euler equations is presented. The algorithm creates an initial uniform mesh and cuts the body out of that mesh. The mesh is then refined ...
