Nonequilibrium Recombination in Nozzles: Fundamental Recombination Processes in Lox-Hydrogen, Fluorine-Hydrogen, and Flox-Hydrogen Propellants,
Abstract
The significant nozzle recombinattion steps are tabulaated for combustion products formed by LOX-hydrogen, fluorine-hydrogen, and FLOX-hydrogen propellants. Kinetic data for each of these 23 nozzle reactions are summarized. A systematic basis is presented for selecting the significant nozzle reactions of atoms, radicals, and molecules for inclusion on the data tapes of computer programs for nonequilibrium calcuclculations of propelellant performance. Thhe relative importance of the pre-exponential factor in high-temperature recombinations is emphasized. A method is given for reducing the number of equations needed in nonequilibrium performance calculations involving termolecular recombinations. A procedure for calculating concentrations of light-emitting excited states in the exhaust is presented. Ionization constants for the formation of cations, anions, and electrons in nozzle gases are computed and discussed briefly. (Author)
