Multiple Ignition, Combustion and Quenching of Hydrocarbon Fuel Sprays

Abstract

Ignition data has been compiled for combustible gaseous mixtures with hot burning particle sources. High-speed photography, Schileren photography and pyrometry have been employed in the diagnostics. The ignition and non-ignition domains in terms of particle size and mixture ratio have been determined. The design and fabrication of the spray ignition experiment is underway. Finite- difference and asymptotic results have been concluded and the ignition domains have been determined with good agreement (within our limitations of knowledge about chemical kinetics) have been obtained. The preliminary theoretical results about spray ignition indicated that minimum ignition energy and ignition delay should be treated as probabilistic parameters.
