The sensitivity of lean combustion to stratification level was studied in a turbulent flow field for the turbulent stratified flames configuration. Differential diffusion caused by the flux of species e.g. H2 was identified for all stratification levels. The effect of stratification onto the flame micro-structure was evident in the pre- heat zone and in the reaction zone as shown by the means of the local equivalence ratio. The temperature profiles in this back-supported configuration were more impacted on the reactant side than on the product side by stratification. In contrast equivalence ratios as well as mass fractions of hydrogen were sensitive to stratification on the product side as well as in the reactants.
