| Abstract: | Based on the GRI-Mech 3.0 mechanism,the premixed laminar combustion characteristics of methane-air-diluent mixtures were investigated by using PREMIXED Code.Several fundamental parameters,such as flame structure,laminar burning velocity,and flame thickness,were calculated at different equivalence ratios,initial pressures,and dilution ratios.It was found that increasing the dilution ratio in the mixture would lead to a decrease in laminar burning velocity and an increase of flame thickness.As a result,the hy... |
