Experimental study of radiative heat transfer in a translucent fuel sample exposed to different spectral sources

June 28, 2013
Author(s)
Gregory T. Linteris, Nicolas Ball, J. Raynard, Guillermo Rein, Jose L. Torero, M. Forsth, P. Boulet, G. Parent, Z. Acem
Radiative heat transfer to a solid is a key mechanism in fire dynamics, and in-depth absorption is especially of importance for translucent fuels. The sample-heater interaction for radiative heat transfer is experimentally investigated in this study with

Nanoparticles in Flame-Retardant Coatings for Flexible Polyurethane Foams: Effects on Flammability and Nanoparticle Release

May 15, 2013
Author(s)
Mauro Zammarano, Rick D. Davis, Yeon S. Kim, Richard H. Harris Jr., Marc R. Nyden, Jeffrey W. Gilman, Nasir M. Uddin
Nanoparticles can effectively reduce polymer flammability; however, the impact of nanoparticles on environmental and health safety is still unclear. The purpose of this study is twofold: (1) to develop and investigate the effect of nanoparticle-rich

Guidelines for Evaluating Fire Blocking Barrier Fabrics

April 18, 2013
Author(s)
Shonali Nazare, William M. Pitts, Shaun M. Flynn, Rick D. Davis, John R. Shields
This document provides guidelines to quantify fire performance properties of fire blocking barrier materials used in soft furnishings. In an attempt to enable a priori selection of fire barrier materials such that the final upholstered product complies

Thermal and Burning Properties of Poly(lactic acid) Composites Using Cellulose-Based Intumescing Flame Retardants

December 21, 2012
Author(s)
Douglas M. Fox, Srilatha Temburni, Melissa Novy, Laura Flynn, Mauro Zammarano, Yeon S. Kim, Jeffrey W. Gilman, Rick D. Davis
Poly(lactic acid) was flame retarded using cellulose-based intumescing flame retardants. Cellulose was an excellent carbon source in combination with ammonium polyphosphate (APP), exhibiting good thermal stabilities and UL-94 ratings of V-0

Cup-Burner Flame Structure and Extinguishment by C2HF5 in Microgravity

September 26, 2012
Author(s)
Gregory T. Linteris, Fumiaki Takahashi, Viswanath R. Katta, Oliver Meier
The effects of fire-extinguishing agent C2HF5 (pentafluoroethane, HFC-125) added to a coflowing airstream on the structure and extinguishing processes of microgravity cup-burner flames have been studied numerically. Propane and a propane-ethanol-water fuel

Factors Influencing the Smoldering Performance of Polyurethane Foam

September 26, 2012
Author(s)
Mauro Zammarano, Szabolcs Matko, Roland H. Kraemer, Rick D. Davis, Jeffrey W. Gilman, Shivani N. Mehta
The objective of this study was to evaluate whether polyurethane foam (PUF) could be produced as a standard reference material for ultimate use in a standard test intended to ensure the smoldering performance of commercially available upholstered furniture

Unwanted Combustion Enhancement by C6F12O Fire Suppressant

August 7, 2012
Author(s)
Gregory T. Linteris, Valeri I. Babushok, Peter B. Sunderland, Fumiaki Takahashi, Viswanath R. Katta, Oliver Meier
Several agents are under consideration to replace CF3Br for use in suppressing fires in aircraft cargo bays. In a Federal Aviation Administration (FAA) performance test simulating the explosion of an aerosol can, however, the replacements, when added at

Ionic Liquid Facilitated Introduction of Functional Materials into Biopolymer Polymer Substrates

August 2, 2012
Author(s)
Shonali Nazare, Jeffrey W. Gilman, Mauro Zammarano, Luke Haverhals, W.Matthew Reichert, Hugh De Long, Paul C. Trulove
In addition to being efficient solvents for biopolymers, several ionic liquids (ILs) have been shown to be effective solvents for synthetic polymers such as meta-aramids, i.e., Nomex ® (1-5). In this report, meta-aramid/cotton composites are generated by

Combustion Properties of Halogenated Fire Suppressants

August 1, 2012
Author(s)
Gregory T. Linteris, Valeri I. Babushok, Oliver Meier
Previous experimental studies have shown that some halogenated fire suppressant agents added to hydrocarbon-air systems can enhance the combustion. For example, their addition to the air stream can widen the flammability limits of lean mixtures, and

A Literature Review of the Effects of Fire Smoke on Electrical Equipment

July 31, 2012
Author(s)
Richard D. Peacock, Thomas G. Cleary, Paul A. Reneke, Daniel Murphy
A review is presented of the state of the art of smoke production measurement, prediction of smoke impact as part of computer-based fire modeling, and measurement and prediction of the impact of smoke through deposition of soot on and corrosion of

Absorption and Reflection of Infrared Radiation by Polymers in Fire-Like Environments

July 17, 2012
Author(s)
Gregory T. Linteris, Mauro Zammarano, Boris Wilthan, Leonard M. Hanssen
In large-scale fires, the input of energy to burning materials occurs predominantly by radiative transfer. The in-depth absorption of radiant energy by a polymer influences its ignition time and burning rate. The present investigation examines two methods
