AUTO-IGNITION CHARACTERISTICS OF CONVENTIONAL AND SYNTHETIC ALTERNATIVE JET FUELS IN A MOTORED ENGINE AND AN OPTICALLY ACCESSIBLE CONSTANT VOLUME SPRAY COMBUSTION CHAMBER

摘要

In recent years, synthetic liquid fuels produced from the reforming of coal, natural gas and biomass have been drawing the U.S. military's attention as potential alternatives to current petroleum-derived fuels, such as JP-8 for aviation and F-76 for naval applications. Fuel specification standards dictate requirements on a variety of chemical and physical properties of such alternative fuels to ensure that the fuels will serve well in their application. In addition, understanding the chemical kinetic behavior of alternative fuels, for example ignition delay, flame speed, and extinction limits, is essential for combustion model development.
