| 摘 要： | 针对燃气轮机燃烧室火焰筒中的甲烷-空气贫燃料预混燃烧问题,给出了基于八步化学反应动力学机理的数学模型。以某型航空发动机燃烧室火焰筒为例,对甲烷-空气贫燃料的预混燃烧进行数值模拟。研究结果表明,基于八步化学反应动力学机理的数值模拟方法,可以比较准确地反映燃烧产物的形成过程,在分析航空发动机燃烧室火焰筒内的贫燃料预混燃烧问题时具有较强的实用性。

| Abstract: | In view of the lean-premixed combustion of methane-air in an aero-engine combustor,an eight-step chemical kinetic mechanism model is given.This paper reports the numerical simulation of lean-premixed combustion of methane-air by taking aero-engine combustor liner as an example.The research indicates that precise pollutant prediction can be given perfectly using the model based on the eight-step chemical kinetic mechanism,which is practical for analysis of the aeronautical lean-premixed combustion. |
