摘要 使用Kintecus化学计算软件数值模拟甲烷空气预混燃烧,得到反应过程图像.对燃烧模型中38个反应路径进行了敏感性分析,试图找出简化模型的量化方法,并分析它们对NOx污染物生成的影响.研究发现敏感性分析图像能够更细致、更形象地描述不同反应对于燃烧过程和NOx生成影响的本质,补充了化学反应机理. The CH_4-air premixing combustion is numerically simulated by using Kintecus,a chemical software, and the reaction graphs are obtained.To simplify chemical kinetics,and to analyze the influence of the reactions on the combustion process and NO_x emission,sensitivity analysis is carried on the reaction mechanism of NO_x emission.The results show that sensitivity analysis graphs can better describe the combustion process.
