Accurate modelling of preignition chemical phenomena requires a detailed description of the respective low-temperature oxidative\nreactions.Motivated by the need to simulate a diesel oil spray evaporation device operating in the ââ?¬Å?stabilizedââ?¬Â cool flame regime, a\nââ?¬Å?tabulated chemistryââ?¬Â tool is formulated and evaluated.Thetool is constructed by performing a large number of kinetic simulations,\nusing the perfectly stirred reactor assumption. n-Heptane is used as a surrogate fuel for diesel oil and a detailed n-heptane\nmechanism is utilized. Three independent parameters (temperature, fuel concentration, and residence time) are used, spanning\nboth the low-temperature oxidation and the autoignition regimes. Simulation results for heat release rates, fuel consumption\nand stable or intermediate species production are used to assess the impact of the independent parameters on the systemââ?¬â?¢s\nthermochemical behaviour. Results provide the physical and chemical insight needed to evaluate the performance of the tool\nwhen incorporated in a CFD code. Multidimensional thermochemical behaviour ââ?¬Å?mapsââ?¬Â are created, demonstrating that cool\nflame activity is favoured under fuel-rich conditions and that cool flame temperature boundaries are extended with increasing\nfuel concentration or residence time.
