THE EFFECT OF ADDITIVES ON THE MECHANISM OF DETONATION IN GASEOUS SYSTEMS
Abstract
This dissertation investigates the effect of He, Ar and CO2 additives on the mechanism of detonation in stoichiometric hydrogen-oxygen mixtures over wide ranges of initial pressures and additive concentrations, and attempts to determine the validity of the Chapman-Jouguet thermohydrodynamic theory under these conditions. No quantitative conclusions can be made about whether complete chemical and/or thermal equilibrium in the Chapman-Jouguet plane was established, or to whether the ''frozen'' or ''equilibrium'' product gas sound speed is most correct in the real gas situation. The detonation velocity was slightly dependent on initial pressure but was critically dependent on mixture composition. The experimental detonation static pressures followed the same general trend as the velocities. The theoretical detonation and shock wave pressures and temperatures increased linearly with initial pressure and were relatively independent of mixture composition. Additives retarded the rate of attainment of stable detonation in stoichiometric hydrogen-oxygen mixtures.
