A reduced chemical mechanism for n-dodecane combustion has been calibrated following the methodology presented in . The hybrid mechanism is composed of a fuel-independent core submechanism including C0-C4 chemistry (Aramco Mech 2.0)  and a small fuel-dependent submechanism containing three species and eleven reactions. The fuel-dependent reactions describe both the low and high-temperature fuel decomposition pathways and were calibrated to match ignition delay times computed using a detailed mechanism  over a range of temperatures from 650 to 1400K, pressures from 1 to 100 bar, and equivalence ratios from 0.25 to 3. Very good agreement was observed between the reduced mechanism and the detailed mechanism. Importantly, the reduced mechanism captures the low-temperature heat release and NTC behavior.
