Abstract

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 plug flow reactor, in a well-stirred reactor and for a premixed laminar flame and were carried out with the Sandia CHEMKIN code. The input data consists of four blocks of rate constant information that describe the C-H-0, C-H-0-F, C-H-0-F-Br, and C-H-0-F-I systems. The specific properties in addition to species concentrations are (a) for the plug flow reactor; the induction delay time and time for destruction of oxidant and fuel, @) for premixed laminar flame; flame velocity, (c) for the well stirred reactor, the self ignition temperature and extinction flow rates The simulations showed that induction times are not an appropriate variable for ranking inhibition efficiency. All the other parameters track known behaviors of inhibition efficiency with good accuracy. The general ordering of inhibition strength is CF,Br, CF,I > GF6 > qHF5 > CHF3 > CF,. with the first two compounds clearly superior to the others.
