Reduced Kinetic Mechanisms and Asymptotic Approximations for Methane-Air Flames: A Topical Volume

by Mitchell D. Smooke (Editor), R.W. Bilger (Contribution by), H.K. Chelliah (Contribution by), J.-Y. Chen (Contribution by), R.W. Dibble (Contribution by)

Overview

In this comprehensive text a systematic numerical and analytical treatment of the procedures for reducing complicated systems to a simplified reaction mechanism is presented. The results of applying the reduced reaction mechanism to a one-dimensional laminar flame are discussed. A set of premixed and non-premixed methane-air flames with simplified transport and skeletal chemistry are employed as test problems that are used later on to evaluate the results and assumptions in reduced reaction networks. The first four chapters form a short tutorial on the procedures used in formulating the test problems and in reducing reaction mechanisms by applying steady-state and partial-equilibrium approximations. The final six chapters discuss various aspects of the reduced chemistry problem for premixed and nonpremixed combustion.
