In this study an axisymmetric RANS simulation of a bluff-body stabilised flame has been attempted using both steady and unsteady flamelet models. Reynolds Stress Model has been used for turbulence closure. Unsteady effects are considered in a post-processing manner through the Eulerian Particle Flamelet Model (EPFM). Comparison of steady and unsteady results show that transient effects do not have much influence on major species, including OH and structure of the flame and therefore can be successfully predicted by steady or unsteady approaches but slow process like NO formation can only be captured if unsteady effects are taken into account while steady simulation tend to significantly overpredict NO.
