抄録

Recently a lean-rich combustion is drawing attention as a way to decrease the level of NO_χ. In the lean-rich combustion flame, the oscillation and the noise is generated by the velocity difference between the lean-side flame and the rich-side flame. This oscillation and the flame structure in the unsteady-state have not been made clear. Numerical unsteady-state analysis was performed in order to make clear the flame structure of the methane-air lean-rich combustion flame in unsteady-state. In the lean-rich flames, the lean and the rich slit burners were set side by side in the combustor. A two-dimensional numerical analysis was performed based on skeletal chemistry proposed by Smooke M.D.which includes 35 elementary reactions of 16 chemical species.
