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

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

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

Prediction of the mass loss rate of polymer materials: Impact of residue formation

April 21, 2012
Author(s)
Gregory T. Linteris, Bernhard Schartel, Florian Kempel, Stanislav Stoliarov, Richard E. Lyon, Richard N. Walters, Anja Hofmann
Two different numerical simulation tools, Fire Dynamic Simulator (FDS) and ThermaKin, are investigated with respect to their capability to predict the mass loss rate of polymer materials exposed to different fires. For validation, gasification apparatus

Annual Report to Sponsor: Understanding Unwanted Combustion Enhancement by Potential Halon Replacements

February 3, 2012
Author(s)
Gregory T. Linteris, Jeffrey A. Manion, Donald R. Burgess Jr., Iftikhar A. Awan, Peter B. Sunderland, John L. Pagliaro
This year, we continued work to numerically model the behavior of the Halon replacements in the FAA Aerosol Can Test (FAA-ACT) to understand why they are causing more overpressure rather than flame extinction. The goal is to understand the process to

Effects of Fire Suppressants on Ignition Characteristics of Propane-Air Mixtures

December 6, 2011
Author(s)
Gregory T. Linteris, Viswanath R. Katta, Fumiaki Takahashi, Harsha K. Chelliah, Oliver Meier
A numerical investigation is performed for understanding the ignition behaviors of CF3Br and R- 125 fire-suppressing agents in propane-air-agent mixtures. Two types of simulations are considered in an attempt to provide insight into the FAA’s Aerosol Can
