| 摘要: |
| 以grimech 3.0详细反应动力学机理为基础，计算贫燃甲烷氧化时各个基元反应对关键中间组分的生产与消耗的贡献，并利用敏感性分析的方法研究甲烷氧化过程中各基元反应对整体反应速率的贡献程度。在确定主反应路径的前提下，构建包含16种组分、31步反应的甲烷氧化的简化反应动力学机理，并与详细机理做比较。该简化机理主要适用于当量比在0.2以下的极端贫燃工况。 |

| Abstract: |
| Production rate of important reactants was calculated through grimech 3.0 mechanism in methane oxidation. A sensitivity analysis was employed to determine important elementary reactions in oxidation. A reduced kinetics mechanism for lean methane oxidation was built, including 16 species and 31 steps. Simulation results based on the reduced mechanism were compared with the calculation results of grimech 3.0. The reduced mechanism is suitable for lean fuel condition at an equivalence ratio lower than 0.2. |
