Suppression Effectiveness of Aerosols: The Effect of Size and Flame Type

January 1, 2002
Author(s)
J W. Fleming, B A. Williams, R S. Sheinson
This paper summarizes efforts to identify properties of aerosols (liquids and solids) leading to effective fire suppression. It is part of the US Department of Defense’s Next Generation Fire Suppression Technology Program (NGP) supported by the DoD

Thermodynamics of Metal Agent Fire Extinguishment

January 1, 2002
Author(s)
J D. Mather, R E. Tapscott
The thermodynamics of oxides, carbonates, halides and related metal compounds involved in extinguishment by dry chemicals and metal agents has been analyzed. It is shown that lattice energies play an important role in determining the extinguishment

H V. Oppermann, T L. Grimes
The 86th annual meeting of the National Conference on Weights and Measures will be held in Washington, DC, July 22-26, 2001. The theme of the Conference is Success Through Communication and Cooperation.The National Conference on Weights and Measures

Report on Forum 2000: Fluid Properties for New Technologies - Connecting Virtual Design with Physical Reality

May 14, 2001
Author(s)
James C. Rainwater, Daniel G. Friend, Howard J. Hanley, Allan H. Harvey, C D. Holcomb, Arno D. Laesecke, Joe W. Magee, Chris D. Muzny
Forum 2000, which addressed the present needs and priorities for thermophysical properties measurements, was held June 29, 2000, at the 14th Symposium for Thermophysical Properties in Boulder, Colorado. Seven distinguished experts presented overviews of

Cost Analysis of Fire Suppression Systems

April 24, 2001
Author(s)
J M. Bennett, M L. Kolleck
All three services and their respective platforms have special problems in regard to fires. Each carries munitions, which can be initiated by a fire. In addition, each can also contain large quantities of fuel distributed in fuel tanks throughout, with

On the Suitability of CF3Br as a Benchmark replacement Fire Suppressants

April 24, 2001
Author(s)
B A. Williams, J W. Fleming
We investigate the rationale for the use of CF,Br as a reference standard for alternative fire suppresants. Stating efficiencies of alternative agents on a relative basis to that of CF,Br is well founded from an engineering standpoint, but less so from a

TOWARDS SUBGRID SCALE MODELING OF SUPPRESSANT FLOW IN ENGINE NACELLE CLUTTER

April 24, 2001
Author(s)
P E. DesJardin, J M. Nelson, L A. Gritzo, David R. Keyser, T A. Ghee, J R. Tucker, P J. Disimile
The release and transport of a suppressant agent into an enclosed compartment is sensitive to local geometrical features or “clutter” that is difficult to resolve numerically without using an excessively large CFD grid. Such examples include wire bundles

Transient Application Recirculating Pool Fire, Agent Effectiveness Screen: Final Report

April 24, 2001
Author(s)
William L. Grosshandler, Anthony P. Hamins, Jiann C. Yang, Kevin B. McGrattan, Cary Presser
A three-year research effort has been conducted as part of the Next Generation Program (NGP) to develop a laboratory screening device suitable for predicting the behavior of halon alternatives in full-scale fire suppression experiments. Most of the work

Periodic Table: Atomic Properties of the Elements

March 1, 2001
Author(s)
Robert A. Dragoset
Periodic Table: Atomic Properties of the Elements. This is version 2, which incorporates previously published revisions of mass numbers for some stable isotopes.

Distributed Sensor Fire Detection (NIST SP 965)

February 1, 2001
Author(s)
Thomas G. Cleary, Kathy A. Notarianni
This paper details a case study that utilized model simulations to assess the relative performance benefits of distributed sensing over single-station, single-sensor smoke detection and co-located multi-sensor detection. 500 individual CFAST computer fire
