Mathematical Techniques in Obtaining Reduced Kinetic Mechanisms With Illustration for Methane Flames

摘要: The computational treatment of detailed kinetic reaction mechanisms combustion is very expensive, especially when the objective implementation CFD (Computational Fluid Dynamics) models; therefore, major effort in searching for methods reduction has been observed. In pursuit efficient techniques, various ideas and theories have emerged recent years. Sensitivity analysis, lumping DRG (Directed Relation Graph) are some these which seem to be powerful tools that can assist this challenge. This paper shows strategies, objectively describing their applications on mechanisms. A reduced mechanism methane flames consisting six-step among nine reactive species obtained from skeletal mechanism, consists 25 reactions.
