Abstract : Laser-induced fluorescence (LIF) can be used to measure the small (diatomic and triatomic) free radicals and other transient species that are intermediates in combustion chemistry. LIF can be coupled with detailed computer models of the chemical reaction networks that incorporate a consistent set of reaction rate constants. Doing so leads to an understanding of that chemistry, of predictive value to describe the combustion under conditions difficult to probe experimentally. This report describes the development of LIF techniques, their applications to flames and laser/pyrolysis (LP) kinetics experiments, and rate constant estimation studies for detailed combustion chemistry modeling. The systems studied were those of hydrocarbons burning in nitrous oxide. These contain some of the chemical networks, individual reactions, and intermediate species present in the gas-phase combustion of nitramine propellants such as HMX and RDX.
