基于极小反应网络方法构建燃烧反应机理:JP-10燃料燃烧
Combustion Mechanism Construction Based on Minimized Reaction Network:Combustion of JP-10
摘要
Abstract
JP-10(exo-tetrahydrodicyclopentadiene,C10H16)is widely used as a fuel in detonation engines,missiles,and scramjets due to its low freezing point,high volumetric energy density,and high specific impulse.Most of the JP-10 mechanisms found in literature are detailed mechanisms with a large number of species and reactions,making them difficult to use in high-dimensional numerical simulations.In this study,based on the minimized reaction network(MRN)method,the species and reaction steps from the previously developed C0-C3 mechanism were expanded to construct a JP-10 combustion mechanism with the minimum number of reaction steps and specified number of species,including 36 species and 57 independent reactions.The mechanism employed fully reversible elementary reactions,and the reaction rate constants were described by a dual-parameter form(A,E)of the Arrhenius equation.The mechanism was validated against experimental data,and the results showed that it could reproduce the ignition delay time and laminar flame propagation velocity of JP-10 combustion within a reasonable error range.The mechanism constructed in this study,based on the MRN method and the dual-parameter Arrhenius rate constant approach,combines a small mechanism size with high predictive accuracy.It can provide support for high-fidelity numerical simulations of JP-10 fuel in engineering-scale combustion chambers.关键词
