Reduced Kinetic Mechanisms for Acetylene Diffusion Flames

摘要: Previous studies of acetylene combustion have predominantly focussed on premixed flames, e.g. Frenklach and Warnatz [14.1] Miller Melius [14.2], while little attention has been given to non-premixed or a systematic reduction the chemical kinetics for either case. For flames latter is topic Chap. 7 current book present study using planar counterflow geometry investigate structure acetylene-air diffusion flames. The forms an ideal computationally efficient configuration theoretical investigations in many past performed alkane fuels. Among these are numerical methane-air propane-air with detailed [14.3,14.4] simplified [14.3] – [14.5] chemistry.
