In this study, RANS based axisymmetric simulations of the jet flames, bluff-body flames and swirling flames have been attempted by employing steady and unsteady flamelet models. The jet flames have been studied for pure hydrogen and diluted hydrogen (CO/H2/N2) fuels. The bluff-body flames have been studied for three different fuels CH4/H2, H2/CO and CH3OH. The swirling flame has been investigated for CH4/H2 fuel. The importance of unsteady effects is thoroughly assessed for combustion predictions. The transient effects are considered in a post-processing manner employing the Lagrangian Flamelet Model (LFM) for jet flames and the Eulerian Particle Flamelet Model (EPFM) for recirculating bluff-body and swirling flames.
