摘要:
采用连通法，针对甲烷复杂反应机理，成功地进行了不同水平的机理简化研究。通过建立组分依赖关系的正规化Jacobian矩阵，精确地查明了燃烧组分之间的耦合关系，分别构造出仅包含重要化学路径的两个动力学简化模型，获得的简化机理分别包含227和138个反应，分别涉及39和26种组分。通过对层流预混火焰结构的模拟，所得简化机理和原详细反应动力学机理关于火焰结构的计算吻合很好，计算结果显示，两个简化机理具有较高的模拟精度。
Abstract:
The method of connectivity method was conducted to the reduction of detailed reaction mechanism for methane. An algorithm for the detection of redundant species was examined based on the inspection of the normalized Jacobian, in which the elements provided information about how the timederivative of the concentration of a species changes if the concentration of another species is perturbed. Two reduced mechanisms consisting of respectively an 39 species involved 227 reactions and 26 species involved 138 reactions for methane oxidation, was found to mimic the performance of the detailed mechanism with high fidelity.
