Formatted Abstract/Summary
In the scramjet arena, hydrocarbon fuels are being considered for their endothermic potential and for use in flights where compact, volume critical designs are required at flight speeds at Mach 5+. Long-chain hydrocarbon fuels, such as aviation kerosene, have handling and storage advantages over hazardous and volatile fuels, such as hydrogen, that are more aligned with current flight systems. The objective of this research is to investigate the conditions under which kerosene fuel (JP-8+100) can be used in a supersonic duct at a hyper velocity impulse facility. Experimental data on kerosene ignition lengths for temperatures in the range 1100–1550 K, pressure of 1 atm, and equivalence ratios of 0.2–2.5 are compared with ignition delay correlations from literature. The primary aim of the research is an examination of experimental results for the ignition delay times wben kerosene is augmented by the addition of 0.14-0.86 mole fraction of ethylene. It will be demonstrated that ethylene augmentation does not in any significant manner assist ignition of the kerosene. In contrast, it is shown that the ignition times of kerosene dominate and suppress the ignition of ethylene.
