Numerical Simulation of Miscible and Immiscible Fluid Flows in Porous Media
(University of Texas at Arlington, 1981-02)
**Please note that the full text is embargoed** ABSTRACT: Fast, economical, and accurate finite difference numerical methods are developed for approximating continuum
models of both miscible and immiscible fluid flows ...
Particle Simulation in Contact Mechanics of a Bouncing Elastic Ball
(University of Texas at Arlington, 1999-05)
An elastic ball is simulated by considering lumped mass molecular sets called particles. Particles are allowed to interact only locally in a fashion similar to that employed in molecular mechanics. Under local and gravity ...
Molecular Mechanics Simulations of the Three Dimensional Cavity Problem
(University of Texas at Arlington, 1999-03)
The rapid development of computer technology has resulted in broad interest in three dimensional fluid simulation, which is known to have more complex force interactions than occur in two dimensions (see, e.g., refs. [1-6], ...
Rapid Computation of the Energy States of Two-Electron Atoms and Ions with an Explicit Formula for the Excited States of Helium
(University of Texas at Arlington, 1985-05)
**Please note that the full text is embargoed** ABSTRACT: A new computational approach is
developed for the energy states of
two electron atoms and ions. The
theory incorporates a classical
interpretation of electron ...
Semiclassical Modeling of the States and Spectra of Para Hellium Singlets
(University of Texas at Arlington, 1985-12)
**Please note that the full text is embargoed** ABSTRACT: It is commonly believed that the excited states of helium are solutions of the Schroedinger equation for helium. We show first that this is, in general, false by ...
Accurate Quasi-Quantum Mechanical Numerical Methodology
(University of Texas at Arlington, 1990-10)
**Please note that the full text is embargoed** ABSTRACT: A quasi-quantum mechanical method in which energy is determined
by quantum mechanics and motion by Newtonian mechanics is
studied by combining it with numerical ...
An Elementary Algebraic Method for Approximating Average Radii of First and Secong Ring Electrons
(University of Texas at Arlington, 1984-11)
**Please note that the full text is embargoed** ABSTRACT: In this paper, experimental ionization energies are used to
determine algebraic equations whose solutions approximate
relativistic quantum mechanical estimates ...
Molecular Cavity Flow
(University of Texas at Arlington, 1998-01)
**Please note that the full text is embargoed** ABSTRACT: Using molecular mechanics, cavity flow is studied in a basin of 4235 water molecules at 15°C. Primary vortices are generated with wallspeeds [see pdf for notation]. ...
A Molecular Mechanics Simulation of Cracks and Fractures in a Sheet of Ice
(University of Texas at Arlington, 1998-07)
**Please note that the full text is embargoed** ABSTRACT: Rectangular, two dimensional sheets of ice molecules are both stressed and compressed. Computer examples compare dynamical responses when the plate has a slot or ...
Mathematical Models of Porous Flow
(University of Texas at Arlington, 1978-10)
**Please note that the full text is embargoed** ABSTRACT: In this paper a new, viable mathematical approach to the analysis
of porous flow is developed. Liquids and solids are modeled as
sets of particles which interact ...
