摘要
基于自主研发的碳氢燃料燃烧机理自动简化软件ReaxRed~[1]对Metcalfe等构建的包含329个物种,1888个基元反应甲苯燃烧模型~[2]进行系统简化。简化方法采用直接关系图法(DRG)、基于CSP重要性指标的冗余反应移除方法和基于CSP理论的准稳态方法~[3]。最后,得到包含50物种、133反应的框架模型和39物种、35反应的简化模型。模拟结果显示,在较宽的参数范围内,简化模型能重现甲苯燃烧的点火延迟等燃烧特性的预测;得到的简化模型将可能用于CFD模拟。
Using automatic reduction software ReaxR ed for hydrocarbon fuels combustion mechanism, the skeletal mechanism including 50 species and 133 elementary reactions and the reduced mechanism with 39 species and 35 reactions are derived by using ReaxR ed program page from the detailed mechanism consisting of 329 species and 1888 elementary reactions. The reduced mechanism can reproduce combustion characteristics of the detailed mechanism such as the ignition delay time, distribution of temperature over a wide range of simulation conditions. The 39-species mechanism of toluene may be used in computational fluid dynamics(CFD).
