Non-premixed turbulent reacting flow in a methane-fuelled coaxial jet combustor has been studied numerically employing Reynolds Averaged Navier-Stokes (RANS) models. A Local Extinction approach for treating chemical reaction kinetics within the Eddy Dissipation Concept (EDC) has been examined. It applies a database of pre-calculated chemical time scales, which contains the influence of chemical kinetics that is otherwise time-consuming to calculate. Simulations were carried out using RNG k-epsilon turbulence models by open-source CFD-toolbox OpenFOAM. The results were compared to available numerical results and experimental data for velocity, and temperature fields. All simulations were conducted with a reasonable number of mesh to demonstrate the accuracy of turbulent RANS models in OpenFOAM solver, which has a wide range of engineering applications in such type of flows.
