✦ Synopsis

A four-step mechanism for the combustion of methane in air in nonpremixed flames is obtained by making steadystate and partial equilibrium approximations for minor species. The model gives good predictions of laminar flame structure, including steady-state minor species, for a wide range of flame stretch and across the whole breadth of the reaction zone, including rich mixtures. A good prediction of extinction is obtained. Further reduction to a three-step or two-step mechanism is discussed.

A post-processing method to predict NO formation in one-and two-dimensional flames is developed. A flame calculation with a reduced number of species and reactions is performed first. The remaining species are computed in a post-processing step. The computational effort is reduced further by introdu

proposed a model for the flammability limits of an upward propagating flame through lean CHa/air mixture in a standard round tube. The construction of the model was based on information that extinction first occurs at the tip of the flame where the flame stretch is maximum. In their mathematical des
