Reduced Kinetic Mechanisms and Asymptotic Approximations for Methane-Air Flames

This topical volume is the first to address in a systematic way the simulation of combustion phenomena in chemical research and engineering. The authors give a systematic presentation of numerical and analytical problems of the reduction mechanism for complex chemical reactions and for complicated transport phenomena applied to one-dimensional laminar flames.
