Chemical Kinetics and Fire

October 7, 2015
Author(s)
Gregory T. Linteris, John Griffiths
The purpose of this chapter is to set out the principles of chemical kinetics as they apply to combustion in flames and fires. Chemical equilibrium, which was discussed in a previous chapter, deals with the final preferred state of a given set of reactants

A Chemical Kinetic Mechanism for 2-Bromo-3,3,3-trifluoropropene (2-BTP) Flame Inhibition

July 22, 2015
Author(s)
Donald R. Burgess Jr., Valeri I. Babushok, Gregory T. Linteris, Jeffrey A. Manion
The present paper is concerned with the development of a detailed chemical kinetic mechanism to describe the flame inhibition chemistry of the fire suppressant 2-bromo-3,3,3-trifluoropropene (2-BTP). Currently 2-BTP is considered as a fire suppressant to

Enhancement of Premixed Methane-Air Flames by Halon 1301 Replacements

May 16, 2015
Author(s)
John L. Pagliaro, Gregory T. Linteris, Peter B. Sunderland
Apparent combustion enhancement by some halon replacement fire suppressants (proposed for use in aircraft cargo bays) has been observed in full-scale, constant-volume tests at the FAA. In order to explore the phenomena, laboratory-scale constant-volume

Exothermic Reaction of Halogenated Hydrocarbons: WORKSHOP PROCEEDINGS

March 13, 2015
Author(s)
Gregory T. Linteris, Jeffrey A. Manion
A workshop was held at NIST Gaithersburg on October 27 and 28, 2014 to discuss the exothermic reaction of halogenated hydrocarbons. The industries that gathered to discuss the topic were the fire suppression, fire suppression in aircraft, and Heating

Experimental and Numerical Simulations of the Gas-Phase Effectiveness of Phosphorus Compounds

February 2, 2015
Author(s)
Nicolas Bouvet, Gregory T. Linteris, Valeri I. Babushok, Fumiaki Takahashi, Viswanath R. Katta
The effectiveness of phosphorus-containing compounds as gas-phase combustion inhibitors varies widely with flame type. To understand this behavior, experiments are performed with dimethyl methylphosphonate (DMMP) added to the oxidizer stream of methane-air

Hydrocarbon Flame Inhibition by C3H2F3Br (2-BTP)

November 14, 2014
Author(s)
Valeri I. Babushok, Gregory T. Linteris, Donald R. Burgess Jr., Patrick T. Baker
The kinetic mechanism of hydrocarbon flame inhibition by the potential halon replacement 2-BTP has been assembled, and is used to study its effects on premixed methane-air flames. Simulations with varying CH4-air stoichiometry and agent loading have been

Modeling of 2-bromotrifluoropropene flame inhibition

August 14, 2014
Author(s)
Donald R. Burgess Jr., Jeffrey A. Manion, Valeri I. Babushok, Gregory T. Linteris
We developed a new chemical mechanism for modeling flame inhibition by 2-bromotrifluoropene (2-BTP). The modeling results qualitatively predicted agent behavior in cup-burner and FAA Aerosol Can tests over a wide range of conditions. The ban on igh ozone

Influence of Flame Characteristics on Gas- Phase Fire Retardant Effectiveness

May 30, 2014
Author(s)
Gregory T. Linteris, Nicolas Bouvet, Valeri I. Babushok, Fumiaki Takahashi, Viswanath R. Katta, Stanislav Stoliarov, Peter B. Sunderland
The presentation discusses the influence of flame characteristics on gas-phase fire retardant effectiveness. First, the action of super-effective agents in co-flow diffusion flames is reviewed, highlighting how particle formation had a detrimental effect

Flame Inhibition by CF3CHCl2 (HCFC-123)

May 20, 2014
Author(s)
Valeri I. Babushok, Gregory T. Linteris, Oliver Meier, John Pagliaro
A kinetic model is suggested for hydrocarbon-air flame propagation with addition of hydrochloroflurocarbon (HCFC) fire suppressants, encompassing the combined chemistry of fluorine- and chlorine-containing species. Calculated burning velocities using the

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

Author(s)
Gregory T. Linteris, Valeri I. Babushok, Fumiaki Takahashi, Viswanath R. Katta, Oliver Meier
Several fire suppressants are under consideration to replace CF3Br for use in suppressing fires in aircraft cargo bays. In Federal Aviation Administration performance tests simulating the explosion of an aerosol can, however, the replacements HFC-125, 2-

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)
