Polyurethane flexible foams (PUFs) have a large market as upholstery and bedding cushioning material. There is an increasing demand for flame retarded grades in rail, plane and automotive transportation. Untreated PUFs are prone to rapid fire growth due to
The application of quantum mechanics and molecular simulation methods can yield new insights into thermal reactivity and its effect on materials flammability. One example of this approach is reactive molecular dynamics as implemented in a computer program
Occupants in fire emergencies in buildings are presented with multiple pieces of information and environmental cues which produce varying levels of stress for the occupant. Occupants develop behavior response strategies to decrease their level of stress
These four chapters are part of a larger book on radiant heating and cooling. The goal of these chapters is to explain thermal comfort, how it is modeled, and how to calculate it. The first chapter explains the variables of thermal comfort. The second

A quiet revolution is occurring in the field of polymer science the high throughput (HT) or combinatorial revolution. It is, in a general sense, a change in the way one views performing research and development, and simply involves devising methods to

The high throughput mindset has been our approach to rapidly synthesize, characterize, and analyze additive filled polymers. For example, rather than taking a week to extrude polystyrene strands with 0% to 10% integer amounts of organically modified clay

An overview of the research directed at the development and application of high-throughput methods for multi-component polymer blends and nanocomposites that is currently underway in the Building and Fire Research Laboratory is presented.

Firebrands or embers are produced as trees and structures burn in wildland/urban interface (WUI) fires. Hot firebrands ultimately come to rest and may ignite fuels far removed from the fire, resulting in fire spread. It is believed that firebrand showers
The results of NIST s three-year investigation into the collapse of the World Trade Center on September 11, 2001 were published in 2005 in 43 volumes consisting of over 10,000 pages. The reports included 30 recommendations for changes to codes, standards
One of the recommendations of the National Construction Safety Team for the Federal Building and Fire Safety Investigation of the World Trade Center Disaster (NIST NCSTAR 1, 2005) is to enhance the capability of available computational software to predict
The Minerals Management Service (MMS), U.S. Department of Interior, is designated as the lead agency for in situ burn research in the Oil Pollution Research and Technology Plan prepared under the authority of Title VII of the Oil Pollution Act of 1990 (OPA
The consistency of measurements performed in various wind tunnels is of concern to both design engineers and code writers. This study makes an initial attempt at quantifying the variability of wind effects estimates based on tests conducted at six wind
ISO Technical Committee TC 59, Building Construction, is an international standards committee dealing with general rules for performance requirements for buildings, SC 14, Design Life, is the subcommittee of TC 59 that deals with standardization of the
A series of measurements and performance evaluations has been conducted in the Temperature Control Module (TCM) for three control system vendors in order to demonstrate their ability to meet the high accuracy temperature control specification for the

The process of dispersing ionic liquid modified montmorillonite in polylactide (PLA) using a twin-screw micro-compounder under different melt-compounding parameters was monitored using laser scanning confocal microscopy (LSCM). In addition the PLA-MMT
Kinetics of heptane combustion was studied through numerical modeling. High temperature kinetic model of heptane combustion was constructed. The model includes four main blocks of reactions: C1-C2 chemistry, which is based on Grimech-3.0 model; block of C3
This letter contains a discussion of the article in the May-June 1999 issue of the ACI Materials Journal on the Investigation of Chloride Diffusion for High-Performance Concrete Containing Fly Ash, Microsilica and Chemical Admixtures, by Zongjin Li, Jun
There has been a great deal of recent experimental and, particularly, theoretical interest in the development of spatial and temporal oscillations in laminar diffusion flames. Studies indicate that the onset of oscillations (known as Hopf bifurcations) is

The optical extinction of infrared radiation by a water spray has been investigated both experimentally and theoretically. A theoretical analysis based upon Mie theory for spatially inhomogeneous, polydisperse droplet ensembles was used to predict the
The extinction and structure of non-premixed flames were investigated through the comparison of experiments and calculations using a counterflow configuration. Experiments were conducted at the NASA Glenn Research Center s 2.2 s drop tower to attain
