Oxidation and Ignition Characteristics of Hydrocarbon Fuels
A research program studying the oxidation and ignition characteristics of hydrocarbon fuels has been conducted. The program was initiated in October 1985 with the awarding of a research grant through the Army Research Office (Grant No. DAAG 29-85-K-0253, Project No. 22437-EG) and ran through November 1989. The research program entailed mechanistic studies examining the oxidation chemistry of si...
متن کاملAn Experimental Investigation of Hot Surface Ignition of Hydrogen and Hydrocarbon Mixtures in Air
Hot surface ignition was examined using a variety of heat sources in a series of premixed hydrocarbon, hydrogen, and air mixtures. Building off previous work, hexane-air, heptane-air and hydrogen-air experiments were performed in addition to the eventual hexane-hydrogen-air mixtures. Using high-speed schlieren photography, thermocouples, and a fast-response pressure transducer, flame characteri...
متن کاملKinetics Paths to Radical-induced Ignition of Methane/air Mixtures
Non-equilibrium plasmas may be used to dissociate reactants into radicals. In turn, these radicals react releasing energy and broadening the radical pool and thereby ignite or aid the ignition of a fuel=air mixture. Using methane as an archetypical fuel, this work studies the kinetic pathways that control homogeneous ignition in the presence of radicals, which were previously formed by external...
متن کاملExplosion pressures of hydrocarbon-air mixtures in closed vessels.
An experimental study on pressure evolution during closed vessel explosions of several gaseous fuel-air mixtures was performed, at various initial pressures within 0.3-1.2 bar and ambient initial temperature. Explosion pressures and explosion times are reported for methane-, n-pentane-, n-hexane-, propene-, butene-, butadiene-, cyclohexane- and benzene-air mixtures. The explosion pressures meas...
متن کاملG-Scheme-based Analysis of Hydrocarbon Ignition
Using the G-Scheme, we have developed a specific procedure to generate simplified mechanisms for chemical kinetics processes, to analyze them in order to understand the role of the most important reactions, and to identify the most important reactions paths of the processes. The procedure is based on participation indices specifically created for a GScheme generated database. The effectiveness ...
