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

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

The Exothermic Reaction of Fire Suppressants

March 13, 2013
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-

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
