Interaction Mode Change According to the Equivalence Ratios in the Interacting Methane and Hydrogen Counterflow Premixed Flames

상호작용하는 대향류 메탄 및 수소 예혼합화염에서 당량비 조건에 따른 상호작용 모드 변화

The interaction between methane and hydrogen premixed flames with the different equivalence ratio and global strain rate was investigated numerically in one-dimensional counterflow field. The OPPDIF code and GRI-v3.0 were used to simulate the interacting flames. Overall trends in the maximum heat release rates of $CH_4{^-}$ and $H_2$-side flame were examined with the variation of $a_g$. The interaction mode of the flames were classified according to the equivalence ratios and Lewis numbers of each flame and global strain rate.
