摘要

A new second-order moment model for turbulent combustion is applied in the simulation of methane-air turbulent jet flame.The predicted results are compared with the experimental results and with those predicted using the wellknown EBU-Arrhenius model and the original second-order moment model.The comparison shows the advantage of the new model 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.
