heal.abstract	Seven n-heptane oxidation chemical kinetic mechanisms of varied complexity are compared aiming to assess their performance in simulating the cool flame oxidative behaviour of diesel oil, as well as to investigate the validity of the utilization of n-heptane as a "surrogate fuel" for diesel oil. Computed temperature and species concentrations are compared to three different experimental data sets, corresponding to a range of perfectly stirred and plug flow reactor configurations, used for studying the low-temperature oxidation regime of n-heptane and diesel oil. In the cases of n-heptane oxidation, the quality of the kinetic mechanism predictions is found to decline with decreasing pressure levels. The detailed kinetic mechanisms outperform the predictions of the reduced mechanisms, exhibiting, however, discrepancies with the experimental data. In the case of diesel oil stabilized cool flame oxidation, detailed mechanisms fail to reproduce the observed thermo-chemical behaviour, whereas predictions of less detailed schemes show reasonable levels of agreement with the measurements, thus highlighting the limitations of the frequently utilized 6 surrogate fuel" assumption.
