Using a consistent coupling of the ILDM-method for the chemical kinetics with the G-equation approach for describing the flame front propagation, the kinetic effects in the post-flame region of turbulent premixed flames are investigated. Turbulent flow and mixing fields are described by means of first order moment closures, whilst a multidimensional presumed PDF approach is applied to capture the turbulence-chemistry interaction. Mean scalar quantities of both side of the premixed flame front are calculated based on reaction progress variables conditioned on the G-evolution equation. The model derived, very well applicable to premixed and partially premixed flames, is used to simulate a turbulent premixed methane/air flame. A fair agreement with experimental data for major concentration fields and minor species could be achieved. Apparently, the coupling to the G-equation does not provide more additional accuracy in a case where the consideration of piloting plays a non negligible role.
