Errata for NIST NCSTAR 1A, NIST NCSTAR 1-9, and NIST NCSTAR 1-9A, Federal Building and Fire Safety Investigation of the World Trade Center Disaster: Structural Fire Response and Probable Collapse Sequence of World Trade Center Building 7

January 30, 2009
Author(s)
Therese P. McAllister
Errata to the NIST Reports of the Federal Building and Fire Investigation of the World Trade Center Disaster,NCSTAR 1A, NIST NCSTAR 1-9, and NIST NCSTAR 1-9A. (January 2009, April 2012 and June 2012) These changes do not alter the findings, conclusions, or

Fire Fighting Tactics under Wind Driven Conditions: Laboratory Experiments

January 21, 2009
Author(s)
Daniel M. Madrzykowski, Stephen Kerber
Eight full scale experiments were conducted to examine the impact of wind on fire spread through a multi-room structure and examine the capabilities of wind control devices (WCD) and externally applied water streams to mitigate the hazard. The principle

Properties of Smoke from Overheated Materials in Low-Gravity

January 20, 2009
Author(s)
David L. Urban, Gary A. Ruff, Thomas Cleary, Jiann Yang, George Mulholland, Zeng-guang Yuan
Smoke particle size measurements were obtained under low-gravity conditions by overheating several materials typical of those found in spacecraft. The measurements included integral measurements of the smoke particles and physical sample of the particles

Target Penetration of Laser-Based 3D Imaging Systems

January 19, 2009
Author(s)
Geraldine S. Cheok, Kamel S. Saidi, Marek Franaszek
The ASTM E57.02 Test Methods Subcommittee is developing a test method to evaluate the ranging performance of a 3D imaging system. The test method will involve either measuring the distance between two targets or between an instrument and a target. The

Capillary Rise between Planar Surfaces

January 14, 2009
Author(s)
Jeffrey W. Bullard, Edward J. Garboczi
Minimization of free energy is used to calculate the equilibrium verticalrise and mensicus shape of a liquid column between two closelyspaced, parallel planar surfaces that are inert and immobile. States of minimum free energy are found using standard

Effect of CuO Nanolubricant on R134a Pool Boiling Heat Transfer

January 6, 2009
Author(s)
Mark A. Kedzierski, M Gong
This paper quantifies the influence of CuO nanoparticles on the boiling performance of R134a/polyolester mixtures on a roughened, horizontal, flat surface. Nanofluids are liquids that contain dispersed nano-size particles. A lubricant based nanofluid

Clean Agent Suppression of Energized Electrical Equipment Fires

January 1, 2009
Author(s)
Gregory T. Linteris
The NFPA 2001 standard on the use of clean agents for the suppression of fires arose from the phase-out of Halon 1301. Standard methods exists for specifying the amount of clean agent required for Class A and Class B fires, but the recommendation for Class

Stairwell Evacuation from Buildings: What We Know We Don't Know

January 1, 2009
Author(s)
Richard D. Peacock, Jason D. Averill, Erica D. Kuligowski
Occupant descent down stairwells during building evacuations is typically described by measurable engineering variables such as stairwell geometry, speed, density, and pre-evacuation delay. In turn, predictive models of building evacuation use these

Facility Interface to the Smart Grid

December 31, 2008
Author(s)
David G. Holmberg
Homes, commercial buildings and the industrial sector together represent 100 percent of the load on the electric grid. Beyond load, these facilities provide a growing amount of electric generation and storage in the form of distributed energy resources

Durability of Building Joint Sealants

December 12, 2008
Author(s)
Christopher C. White, Kar T. Tan, Donald L. Hunston
Predicting the service life of building joint sealants exposed to service environments in less than real times has been a need of the sealant community for many decades. Despite extensive research efforts have been made to design laboratory accelerated

Smokeview: A Visualization Tool for Understanding Fire Dynamics

December 1, 2008
Author(s)
Glenn P. Forney
The purpose of fire modeling is to gain a better insight into fire dynamics and how it impacts fire safety -- not to generate large amounts of data. Gaining this insight requires visualization tools that display what the numbers generated by the model
