Ne. Ermolin et Ve. Zarko, Investigation of the properties of a kinetic mechanism describing the chemical structure of RDX flames. I. Role of individual reactions and species, COMB EXPL R, 37(2), 2001, pp. 123-147
For description of the chemical structure of RDX flames, key reactions and
species are selected by numerical solution of the system of equations descr
ibing one-dimensional flows of a viscous, heat-conducting, reacting gas at
pressures of 0.5-90 atm. The kinetic mechanism consists of 263 elementary s
teps and 43 species. Literature data on rate constants of elementary steps
are considered. Flame structure is calculated for RDX combustion under irra
diation. Various reaction paths in the RDX vapor decompositon zone are cons
idered. The effects of the mass flow rate and two-dimensional nature of the
gas flow on the flame structure are discussed. Calculation results are com
pared to experimental data. The structure of various flame zones and the ro
le of individual steps and species in the chemical process are investigated
.
