Chemical kinetics of hydrocarbon oxidation in gaseous detonations

Abstract A theoretical model including a detailed chemical kinetic reaction mechanism for hydrocarbon oxidation is used to examine detonation properties for mixtures of fuelair, fueloxygen, and fueloxygen diluted with varying amounts of nitrogen. Fuels considered are methane, ethylene, acetylene, and methanol. Computed induction lengths are compared with available experimental data for critical energy and critical tube diameter for initiation of detonation, as well as detonation limits in planar, cylindrical, and spherical configurations.
