A comprehensive three-year research program was carried out on the characterization of fundamental properties of jet and rocket fuel flames under engine-relevant conditions with increased accuracy and well-defined uncertainties for the first time. The results of the proposed work contributed notably towards the development of real fuel kinetics. Specifically, the following were accomplished 1 A newly developed approach was implemented to measure laminar flames speeds. The approach involved experiments of spherically expanding flames in constant volume vessels in tandem with direct numerical simulations that allow for the accurate characterization of stretch effects and radiation. Measurements were carried out for pressures up to15 atm and unburned reactant temperatures up to 750 K without decomposing the fuel during the compression stage of the experiment 2 Measurements of extinction strain rates were carried out in the counter flow configuration at 1 atm for unburned reactant temperatures up to 500 K and 3 The data were modeled using state of the art codes and in close collaboration with the kinetics teams that are responsible for developing real fuels kinetics.
