Ranking Interventions to Improve Inner-City Housing Indoor Air Quality

June 24, 2005
Author(s)
Steven J. Emmerich, Cynthia H. Reed
The U.S. Department of Housing and Urban Development (HUD) has identified a need to improve urban housing conditions to protect children s health through its Healthy Homes Initiative (HHI). One critical area within this program is to address a wide range

Improved Radiation and Combustion Routines for a Large Eddy Simulation Fire Model

June 16, 2005
Author(s)
Kevin B. McGrattan, J E. Floyd, Glenn P. Forney, Howard R. Baum, Simo A. Hostikka
Improvements have been made to the combustion and radiation routines of a large eddy simulation fire model maintained by the National Institute of Standards and Technology. The combustion is based on a single transport equation for the mixture fraction

High-Temperature Guarded Hot Plate Apparatus Control of Edge Heat Loss

June 1, 2005
Author(s)
Daniel R. Flynn, William M. Healy, Robert R. Zarr
The guarded hot plate (GHP) apparatus is the most common type of absolute apparatus for measurement of the thermal transmission properties of thermal insulation. As the name implies, the hot meter plate is surrounded by a coplanar guard plate, separated by

High-Temperature Guarded Hot Plate Apparatus Optimal Locations of Circular Heaters

June 1, 2005
Author(s)
Daniel R. Flynn, William M. Healy, Robert R. Zarr
The National Bureau of Standards (now the National Institute of Standards and Technology (NIST)) pioneered the use of circular line-heat-sources in guarded hot plate (GHP) apparatus, the most common type of absolute apparatus for measurement of the thermal

Mass Flow Rate of R-410A Through Short Tubes Working Near the Critical Point

June 1, 2005
Author(s)
Y Kim, William V. Payne, John Choi, Piotr A. Domanski
Experimental data were taken to examine R-410A mass flow rate characteristics through short tube restrictors at upstream pressures approaching the critical point. Four short tube restrictors were tested by varying upstream pressure from 2619 kPa to 4551

Modeling Solid Sample Burning With FDS

June 1, 2005
Author(s)
Gregory T. Linteris, L W. Gewuerz, Kevin B. McGrattan, Glenn P. Forney
Black PMMA was burned in the cone calorimeter in two orientations (horizontal and vertical), at imposed radiant heat fluxes of (0, 5, 10, 25, 50, and 75) kW/m2, and the visual appearance, flame size, heat release rate, and mass loss rate were recorded

Preparation of Homogeneously Dispersed Trialkyl Imidazolium Compatibilized Multi Walled Carbon Nanotube/Polystyrene Nanocomposites via Melt Extrusion

June 1, 2005
Author(s)
S Bellayer, Jeffrey W. Gilman, Naomi Eidelman, S Bourbigot, X Flambard, D M. Fox, Hugh C. De Long, Paul C. Trulove
Trialkylimidazolium-tetrafluoroborate, (IM) compatibilized, multiwalled carbon nanotubes (MWNT) were used to prepare well dispersed polystyrene (PS) IM-MWNT nanocomposites via melt extrusion. Quantitative TEM image analysis revealed superior dispersion of

Thermal Imaging Research Needs for First Responders: Workshop Proceedings

June 1, 2005
Author(s)
Francine K. Amon, Nelson P. Bryner, Anthony P. Hamins
This workshop provided a forum to discuss the strategies, technologies, procedures, best practices, research and development that can significantly improve thermal imaging technology. The goal of the workshop was to identify barriers that impede advances

Anionic Effects in Hot Surface Combustions.

May 24, 2005
Author(s)
W W. Bannister, A Donatelli, F Bonner, F Lai, P Kurup, J Egan, E G. Jahngen, P Muanchareon, W Paramasawat, W Sriseubsai, S K. Chiang, V Kongkadee, S Sengupta, R Nagarajan, N Euaphantasate, V Parma, M Cazeca, E Chen, A Morales

Parameter Affecting the Performance of a Residential-Scale Stationary Fuel Cell System

May 23, 2005
Author(s)
Mark W. Davis, Arthur H. Fanney, Michael J. LaBarre, K R. Henderson, Brian P. Dougherty
Researchers at the National Institute of Standards and Technology (NIST) have measured the performance of a residential fuel cell system when subjected to various environmental and load conditions. The system, which uses natural gas as its source fuel, is

On the Ignition of Fuel Beds by Firebrands.

May 11, 2005
Author(s)
Samuel L. Manzello, Thomas G. Cleary, John R. Shields, Jiann C. Yang
An experimental apparatus has been built to investigate the ignition of fuel beds as a result of impact with burning firebrands. The apparatus allowed for the ignition and deposition of both single and multiple firebrands onto the target fuel bed. The

A Curve-Based Mixed System Rating Method for Unitary Air Conditioners

May 2, 2005
Author(s)
William V. Payne, Piotr A. Domanski
The curve-based method was evaluated based on performance predictions for nine mixed systems, which were also tested by an independent testing laboratory. Capacity predictions were within 5% of the tested values for six of nine mixed systems, and four of
