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.
