摘要
湍流燃烧数值模拟中建立有效的反应动力学机理是非常重要.针对一维稳态层流预混火焰模型,分别采用主成分分析法和总敏感性分析法进行了反应机理的简化,结果表明,主成分分析法进行机理简化要优于总敏感性分析法,是一种有效的反应机理简化方法.
It is very important to establish effective reaction kinetic mechanism by using numerical simulation of turbulent combustion. Reaction mechanisms were reduced by principal component analysis method and global sensitivity analysis method for one dimension steady laminar premixed flame model. The results show that principal component analysis method was a better and more effective method than global sensitivity analysis method for reducing reaction mechanisms.
