Using the
Sandia SENKIN code and the CHEMKIN II program, a numerical analysis of the
chemical kinetic model of Jet fuel was performed in a constant volume adiabatic
reactor at intermediate to high temperatures range of 800 K ≤ TC ≤ 1200 K at lean conditions,
equivalence ratios, φ = 0.3 and 0.5 and chamber pressure of 20 and 25 bar. The
ignition delay time in this scenario was influenced by pressure, temperature,
and the equivalence ratio. The influence of the chamber temperature on the
ignition delay time and the trend of negative temperature coefficient behavior
was observed at a chamber temperature of between 850 K to 950K. Beyond these
set values an Arrhenius behavior was displaced over these ranges of chamber
temperatures, as a result, increasing the chamber pressure and equivalence
ratio significantly cause a reduction in the ignition delay time for both
conditions of pressure and equivalence ratios. It was commonly noted that the
model displayed a single-stage ignition delay time and a negative temperature
coefficient (NTC) and the ignition delay time is significantly affected by
changes in temperature, pressure, and equivalence ratios.
