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

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-

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

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
