- Abstract
- Recently a simplified kinetic mechanism comprised of four overall steps was proposed by Hautman et. al. for propane oxidation. Cursory results using this model led these authors to suggest the model might be extendable to predicting oxidative behavior of higher paraffin hydrocarbons. In this paper, the adequacy of this multi-step mechanism for predicting the energy release rate and major species evolution for n-butane oxidation is investigated. New experimental results obtained in the Princeton turbulent flow reactor are reported for n-butane oxidation over the equivalence ratio range 0.08 to 1.7, and the temperature range 990K to 1200K, at one atmosphere. Models using the original mechanism and parameters proposed by Hautman as well as a new set of parameters specific to n-butane are tested. Comparisons are also made with shock tube ignition delay data at higher temperatures and pressures than those available in the flow reactor.
