    Abstract
  • The ignition delay times of RP-3 kerosene/O2/Ar mixtures within the ignition temperature range of 1100-1600K, at pressures of 0.1, 0.2, 0.3MPa, and equivalence ratios of 0.5, 1.0, 1.5, were measured behind reflected shock waves, using side-wall pressure and OH auto-luminescence signal measurements in a chemical shock tube. The effects of ignition temperature, pressure and equivalence ratio on the ignition delay time were investigated and the Arrhenius correlations for the ignition delay time of the mixture under different pressures and equivalence ratios were also deduced. The results show that the correlation between the logarithm of the ignition delay time of the mixture and the reciprocal ignition temperature is linear under different pressures and equivalence ratios. At the same time, with the increase of ignition temperature and pressure and the decrease of equivalence ratio, the ignition delay time of the mixture is shortened.
