Simulation of turbulent piloted methane non-premixed flame based on combination of finite-rate/eddy-dissipation model

Two chemical kinetic mechanisms of methane combustion were tested and compared using a piloted axisymmetric turbulent non-premixed flame: 1-step and 4-step mechanism, to predict the temperature and species distributions. The numerical results are presented and compared with the experimental data. A 4-step methane mechanism was successfully implanted into CFD solver Fluent. The numerical solution is in very good agreement with previous numeral of 4-step mechanism and the experimental data. DOI: http://dx.doi.org/10.5755/j01.mech.19.6.6000
