Inhibition Effectiveness of Halogenated Compounds

January 1, 1998
Author(s)
T Noto, Valeri I. Babushok, Anthony Hamins, Wing Tsang
A numerical study of the inhibition efficiency of halogenated compounds was carried out for C1-C2 hydrocarbon-air laminar premixed flames. The inhibition efficiency of CF3Br, CF3I, CF3H, C2HF, C2F6, and CF4 additives was interpreted using an additive group

CHEMICAL AND PHYSICAL INFLUENCES OF HALOGENATED FIRE SUPPRESSANTS

January 1, 1997
Author(s)
Valeri I. Babushok, Anthony P. Hamins, Wing Tsang, T Noto
The specific mechanisms by which fire suppressants influence flame properties have been determined on the basis of computer simulations. Attention is focussed on the relative contributions from physical and chemical processes. Chemical effects are most

Inhibitor Influence on the Bistability of a CSTR

January 1, 1997
Author(s)
Valeri I. Babushok, T Noto, Donald R. Burgess Jr., Anthony P. Hamins, Wing Tsang
Methane combustion in a continuously stirred flow tank reactor (CSTR) in the presence and absence of chemical inhibitors such as CF3I, CF3Br, CF3H, and a chemically inert gas with high heat capacity is simulated with the CHEMKIN program. The aim of the

Influence of CF3I, CF3Br, and CF3H on the High-Temperature Combustion of Methane

December 1, 1996
Author(s)
Valeri I. Babushok, T Noto, D R. Burgess, Anthony P. Hamins, Wing Tsang
The effects of a number of flame retardants (CF3I, CF3Br, and CF3H) on the high-temperature reactions of methane with air in a plug flow reactor are studied by numerical simulations using the Sandia Chemkin Code. The dependence of (a) the ignition dely and

Effect of Halogenated Flame Inhibitors on C1-C2 Organic Flames

July 28, 1996
Author(s)
T Noto, Valeri I. Babushok, Donald R. Burgess Jr., Anthony P. Hamins, Wing Tsang, A W. Miziolek
The influence of CF3Br, CF3I, CF4, CHF3, C2F6, and C2HF on laminar flame propagation in mixtures of CH4, CH3OH, C2H6, and C2H4 with air has been determined by numerical simulaitons. Comparisons are made with experimental results and earlier calculations

THE INFLUENCE OF HALOGENATED FIRE SUPPRESSANTS ON THE COMBUSTION OF C1-C2 HYDROCARBONS

January 1, 1996
Author(s)
Valeri I. Babushok, Donald R. Burgess Jr., T Noto, Anthony P. Hamins, Wing Tsang, A W. Miziolek
Numerical simulations of the combustion of a number of fuels; (CH,, CH,OH, C2H,, GH, and C&J in air, in the presence and absence of fire suppressants, (CF,Br, CFJ, CF,, Cm3, GF6, and QF5H) have been carried out The simulations considered reactions in a

MODELING OF HYDROGEN FLUORIDE FORMATION FROM FLAME SUPPRESSANTS DURING COMBUSTION

January 1, 1995
Author(s)
Valeri I. Babushok, Donald R. Burgess Jr., Gregory T. Linteris, Wing Tsang, A W. Miziolek
We have completed an initial computational study related to acid gas formation for two of the leading near-term Halon substitutes, FE-13 (CF,H) and HFC-125 (C,F,H), and compared these results with Halon 1301 (CF,Br). Our goal is to determine whether we can
