A laminar flamelet model prediction of a bluff body stabilized CH4/H2 flame is reported. The predicted results of temperature and major and minor species as well as NO are compared against the Raman/Rayleigh/LIF data available from the University of Sydney. The effect of differential diffusion is also studied. The calculation shows that temperature and concentration of major and minor species are better predicted by the unity Lewis number flamelet. It is also shown that the current steady state flamelet approach has difficulties in predicting experimental NO levels.
