Detailed Chemical Kinetic Modeling of n-Heptane Combustion
AbstractDetailed chemical kinetic modeling technique was used to understand the combustion behaviour of n-heptane which is one of the major reference fuel for conventional fuels. Several jet stirred reactor (JSR) experiments from the literature especially in fuel rich conditions (equivalence ratio of 2 and 3) were modeled with various detailed and reduced chemical kinetic models from the literature and the resulting species concentration profiles were compared with the experimental data. Pathway analysis were done to see how the significant reaction types of fuel rich nheptane combustion changes by equivalence ratio. Resulting C2H2 and benzene mole fractions are found to be highly dependent on equivalence ratio. For CO2 and C2H2 formation Wang’s model found to be more accurate on the other hand for CO formation and n-heptane consumption Ranzi’s model gives more proper results.
