Multiple Ignition, Combustion and Quenching of Hydrocarbon Fuel Sprays
Abstract
The objectives were to modify the experimental apparatus so that aromatic fuels such as toluene could be included in the program. It was also intended to continue the theoretical analysis of the ignition of gaseous mixtures and to begin the study of the heterogeneous mixture ignition. In the experiments methane and propane air ignition by burning aluminum particles were studied. In this period of research it was of interest to study the ignition limits of mixtures of air with the vapor of a volatile liquid fuel. This information expanded the data base relevant to ignition of liquid fuel sprays by burning metal particles. Theoretical work on the ignition of gaseous mixtures was completed during this period. Both computational and analytical studies were made. Since delivery of the gas mixtures and vapor mixtures to the combustion chamber were fundamentally different, several modifications to the existing apparatus were made to meet the new objectives of the program. It was of interest to be able to obtain a direct measurement of the temperature of the burning particle. Therefore, the possibility of outfitting the experimental apparatus with an optical pyrometer was examined. (jhd)
