Kinetic Modeling for PAH Formation in a Counterflow Diffusion Flame of Isobutane
27th ICDERS July 28th – August 2nd, 2019 Beijing, China Kinetic modeling for PAH formation in a counterflow diffusion flame of isobutane Wei-Kai Chiua, Hairong Taob, Kuang C. Linc,* aDepartment of Mechanical and Electro-Mechanical Engineering,Kaohsiung 80424, National Sun Yat-Sen University, Taiwan bCollege of Chemistry, Beijing Normal University, Beijing 100875, China cEngineering and System Science,Hsinchu 30013, National Tsing Hua University, Taiwan 1 Abstract In the purpose of understanding the complex chemistry of aromatic hydrocarbon formation in diffusion flames of isobutane oxidation, mechanism that consists of 300 species and 11790 reactions is employed for verifying experimental measurements. The kinetic mechanism is incorporated into a 1-D axisymmetric laminar finite-rate model of a counterflow flame to compute the species profiles. Furthermore, the reaction pathway diagram produced by rate of production analysis illustrates the correlation between the decomposition of isobutane and formation of the target species. Keywords: isobutane, counterflow diffusion flame, paromatic hydrocarbon, chemical kinetic modeling 2 Introduction Isobutane (iC4H10) is an isomer of butane and flammable gas. Although it is not ideal fuel on its own, this species plays a role in the oxidation of large hydrocarbon fuels and is used in liquified natural gas (LNG) [1]. The detailed kinetic mechanism of isobutane combustion contains dozens of species and hundreds of reactions. When a kinetic mechanism is applied to a reaction source term of species transport equations, the computational solutions can be used to describe reactive flows and species distribution in multidimensional reactors. This kind of numerical modeling permits designers and analysts to evaluate emissions and performance of fuels in reactors or combustors. -
