Stability of Voids Formed in Cavities at Liquid-Solid Interfaces

April 1, 2004
Author(s)
Jeffrey W. Bullard
A thermodynamic model is developed of the free energy of gas-filled voids formed within cavities on solid surfaces covered by a liquid. Capillary effects are assumed to be the only important contributions to the free energy, and expressions are derived for

Suppression of Cup-Burner Flames Using Carbon Dioxide in Microgravity

April 1, 2004
Author(s)
V Katta, F Takahashi, Gregory T. Linteris
Carbon dioxide extinguishes flames through dilution process. The extinction characteristics of CO2 were previously studied using a cup-burner flame under normal-gravity conditions. As the diffusion flames behave differently in microgravity compared to

The New DOE Dishwasher Test Procedure: Development and First Results

March 29, 2004
Author(s)
Natascha S. Milesi-Ferretti, J Bowman, B Twigg
This paper summarizes the main changes to the test procedure for residential dishwashers and, Department of Energy s (DOE, Department) and industry s collaborative efforts to develop the data supporting those changes. It also quantifies energy consumption

Building Regulatory Systems in a Post-September 11 World

March 22, 2004
Author(s)
Richard W. Bukowski
The September 11, 2001 attacks in the United States have initiated a significant discussion and rethinking among building regulators not only in the U.S., but also around the world. While most quickly state that regulations should not require that

Pumice Aggregates for Internal Water Curing

March 17, 2004
Author(s)
Pietro Lura, Dale P. Bentz, D Lange, K Kovler, A Bentur
A novel concept in internal curing of High Performance Concrete is based on dispersing very small, saturated lightweight aggregates (LWA) in the concrete, containing sufficient water to counteract self-desiccation. The amount of water in the LWA can be

The Effect of Movement During Cure of a Silicone Sealant

March 8, 2004
Author(s)
Christopher C. White, Donald L. Hunston
Movement of the building joint sealant during cure is thought to affect the fully cured mechanical properties. To examine this potential effect, a one-part silicone sealant was cured from 10 h to 168 h after sample creation before the onset of movement

Structural Collapse Fire Tests: Single Story, Wood Frame Structures

March 1, 2004
Author(s)
D W. Stroup, Nelson P. Bryner, James J. Lee, Jay A. McElroy, G Roadarmel, W H. Twilley
A series of fire tests were conducted in Phoenix, Arizona to develop data for evaluation of a methodology for predicting structural collapse. The fire test scenario was selected as part of a training video being prepared by the Phoenix, Arizona Fire

XML Schema Development Guidelines. Version 1.0

February 1, 2004
Author(s)
Mark E. Palmer, M Burns, T L. Teague
These guidelines summarize the background, rationale and guiding principles that the FIATECH program is using to produce XML domain schemas for automating information exchanges in the capital facilities industries and over the life cycle of equipment used

The NIST 3 Megawatt Quantitative Heat Release Rate Facility

January 12, 2004
Author(s)
Rodney A. Bryant, Thomas J. Ohlemiller, Erik L. Johnsson, Anthony P. Hamins, B S. Grove, William F. Guthrie, Alexander Maranghides
The 3 Megawatt Heat Release Rate Facility was developed at NIST as a first step toward having broad capabilities for making quantitative large scale fire measurements. Such capabilities will be used at NIST to validate fire models and to develop sub-grid

Mobile 3D Visualization for Steel Structures

January 1, 2004
Author(s)
Robert R. Lipman
Until recently, visualization of 3D models required computational resources available only on desktop computers in office environments. With the advance of technology, it is now possible to visualize substantial 3D models on mobile handheld computers in

Predicting re suppression in a simulated engine nacelle

January 1, 2004
Author(s)
J C. Hewson, David R. Keyser
The Vulcan re-eld model is employed to simulate the evolution of pool res and the distribution of re suppressants in a engine nacelle simulator. The objective is to identify conditions for which suppression will and will not be successful in order to (1)

Supression Characteristics of Cup-Burner Flames in Low Gravity

January 1, 2004
Author(s)
F Takahashi, Gregory T. Linteris, V Katta
The structure and suppression of laminar methane air co-flow diffusion flames formed on a cup burner have been studied experimentally and numerically using physically acting fire-extinguishing agents (CO2, N2, He, and Ar) in normal earth (1g) and zero

TIN Techniques for Data Analysis and Surface Construction

January 1, 2004
Author(s)
Christoph J. Witzgall, Javier Bernal, Geraldine Cheok
This report addresses the task of meshing point clouds by triangulated elevated surfaces referred to as TIN surfaces. It describes the general features of this approach, and refers to prototype TIN software employed at NIST for research into the analysis
