Abstrakt: 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.
