Selecting Cost-Effective Green Building Products: BEES Approach

November 1, 1999
Author(s)
Barbara C. Lippiatt
The BEES (Building for Environmental and Economic Sustainability) software implements a rational, systematic technique for balancing the environmental and economic performance of building products. The technique is based on consensus standards and designed

Polymer Layered-Silicate Nanocomposites: Polyamide-6, Polypropylene and Polystyrene

October 24, 1999
Author(s)
Jeffrey W. Gilman, A B. Morgan, Richard H. Harris Jr., E Manias, E P. Giannelis, M Wuthenow
In many of the cases studied, polymer-clay nanocomposites are materials that have improved thermal properties. Furthermore, most of the nanocomposite systems reported so far show reduced flammability. The delaminated versions of nanocomposites also offer

Energy Conserving Discrete Equation for Non-Ideal Systems

October 20, 1999
Author(s)
Nicos Martys
The BBGKY formalism is utilized to obtain a set of moment equations to be satisfied so as to obtain an energy conserving discrete Boltzmann equation for the case of a non-local interaction potential. A modified BGK form of the collision operator consistent

Diffusion in Partially Saturated Porous Materials

October 1, 1999
Author(s)
Nicos Martys
The diffusive transport of ions in two classes of porous media was studied as a function of fluid saturation and wetting properties. A lattice Boltzmann method was used to model phase separation of a binary mixture, including wetting effects, in porous

Effect of Heating Boundary Conditions on Pool Boiling Experiments

October 1, 1999
Author(s)
J Darabi, M M. Ohadi, M A. Fanni-Tabrizi, S V. Dessiatoun, Mark A. Kedzierski
The two widely used experimental methods for pool boiling experiments are evaluated. Boiling heat transfer data employing either the water or electric heating method obtained by various researchers are compared and discussed. The electric heating method is

Energy Conserving Discrete Boltzmann Equation for Nonideal Systems

October 1, 1999
Author(s)
Nicos Martys
The BBGKY formalism is utilized to obtain a set of moment equations to be satisfied by the collision operator in an energy conserving discrete Boltzmann equation for the case of a nonlocal interaction potential. A modified BGK form of the collision

Pore Scale Modeling of Fluid Transport Using Lattice Boltzmann Methods

October 1, 1999
Author(s)
Nicos Martys, John G. Hagedorn, J E. Devaney
The utility of the lattice Boltzmann method for modeling fluid flow in complex geometries like porous materials is examined. After study of some simple test cases, results from large scale simulations of fluid flow through digitized Fontainbleau sandstone

Architecture for Discrete Construction Component Tracking

September 22, 1999
Author(s)
K M. Furlani, William C. Stone
Accurate and timely identification and tracking of construction components are critical to operating a well-managed and cost efficient construction project. Establishing standards to support identification and tracking technologies has the potential to

Finned-Tube Evaporator Model With a Visual Interface

September 19, 1999
Author(s)
Piotr A. Domanski
This paper presents a finned-tube evaporator model and its utility when equipped with a window-based interface. The modeling scheme is tube-by-tube and allows for specification of complex refrigerant circuits, modeling refrigerant distribution between
