### Abstract

Combustion devices mostly rely on turbulent combustion to produce energy in an efficient way. Today computational power has enabled numerical modeling of these real configurations using Large Eddy Simulations(LES). However the scales at which chemical reactions occur are even smaller than the smallest flow scales and require a model. In this work we propose to use spatially filtered 1D laminar flamelet, for simulating a turbulent flame, on a grid coarser than adequate for resolution of chemical scales. A numerical simulation which resolves all the flow and chemical scales is computed as a benchmark and a priori analysis is carried out to test the hypothesis. To test the validity of the model a posteriori analysis using a laminar flame convoluted with top hat is carried out.
