Numerical simulation of methane-air turbulent jet flame using a new second-order moment model

A new second-order moment model for turbulent combustion was applied to the simulation of methane-air turbulent jet flame. The predicted results were compared with the experimental results and with those predicted by using the well known EBU-Arrhenius model and the original second-order moment model. The comparison result shows that it requires almost the same computational storage and time as that of the original second-order moment model, but its modeling results are in better agreement with experiments than those using other models. Hence, the new second-order moment model is promising in modeling turbulent combustion with NOx formation with finite reaction rate for engineering application.
