Order of Heavy-paraffin Auto-Ignition with Respect to Oxygen Concentration Inferred from a "Standard/Available" Kinetic Scheme numerical combustion

wo criteria are becoming increasingly important for kinetic modeling developers. The first one is to write the models in standard format, in order to allow for their test and further development by other scientists. The second one is to make the newly developed models easily available to each universal user in order to have repeatable and comparable results to be implemented and discussed in rational, communicable way by publishing them on the net. Both of these characteristics yield to the use of the model itself as a simple analysis and prediction tool. On the basis of such considerations in the present work a kinetic model satisfying these criteria has been used in order to understand the ignition delay dependence on the chemical kinetics by means of comparison of numerical simulation results with experimental data (de Joannon et al., 1999). Detailed kinetic model of decane oxidation by Battin-Leclerc et al. (2000), available on the web in CHEMKIN format, has been used in the numerical simulation of the chemical ignition delay of a tetradecane spray. The CHEMKIN package (Kee et al., 1989) has been used as computational code and the adiabatic batch configuration (Lutz et al., 1987) has been considered in order to schematize the time-dependent ignition process. The temperature increase ( ?T ) with respect to the initial temperature ( To ) has been chosen as discriminating parameter of ignition occurrence in modeling application.
