The propane sub-model in AramcoMech 1.3 [38] was used for propane flame speed calculations. The kinetic models for n-propanol and propane were reduced systemically with the Princeton Chem-RC software [40] due to memory limitations. A small threshold value of 0.2 was adapted to maintain accuracy. The reduced models were validated against the detailed ones over ITF2357 wide range of temperature, pressure and equivalence ratios for ignition delays and perfectly stirred reactor simulations and differences less than 3% were observed. The kinetic models of Pichon et al. [41] and Veloo et al. [42] were used for acetone and propanal simulations without reduction, respectively.
