Abstract
It is still a challenging task to numerically solve flames using detailed chemical kinetics in multidimensional geometries of practical applications. To overcome this difficulty, many efforts have been done to develop chemical kinetics reducing techniques, such as ILDM, FPV, FPI and FGM. Although these techniques are widely discussed in the literature, their implementation are not straightforward. In the present work the FGM technique is implemented in a two-dimensional laminar premixed flame of CH4/air with heat losses. The temperature, CO mass fraction and burning velocity along the flame surface are presented and limitations of the technique were identified by comparing FGM results against the direct integration of the full set of conservation equation. In general, the FGM technique has shown a good agreement when compared with direct integration.
