A Detailed Kinetic Mechanism of Multistage Oxidation and Combustion of Octanes

Abstract

This study has been focused on the construction of a generalized detailed kinetic mechanism of oxidation and combustion of isoheptane and isooctanes (2-methylhexane, 2-methylheptane, 2,2-dimethylhexane, and 2,2,4-trimethylpentane) to describe both high-temperature reactions and the low-temperature multistage process with separated stages of “cool,” “blue,” and “hot” flames. In accordance with the proposed mechanism, a numerical simulation of autoignition and flame propagation in homogeneous fuel–air mixtures and liquid droplet combustion has been conducted; the calculation results have been compared with the experimental data. Satisfactory qualitative and quantitative agreement of the calculation and experimental results has been obtained.
