Water impact on the auto-ignition of kerosene/air mixtures under combustor relevant conditions

Impact of water (H2O) vitiation on auto-ignition characteristics of kerosene/air mixtures was investigated behind the reflected shock waves covering pressures of 0.45–7.5 atm and temperatures of 900–1450 K. Arrhenius-type expressions were fitted for both mixtures with and without H2O using multiple linear regression method. Temperature- and pressure-dependences of ignition delay times were experimentally observed to be in-line with conventional...
