상호작용하는 대향류 메탄-수소 부분예혼합화염의 CO 배출특성

다국어 초록 (Multilingual Abstract)

The CO emission characteristics of interacting hydrogen and methane partially premixed flames were numerically investigated. A counterflow geometry was introduced to establish interacting two partially premixed flames. An one-dimensional OPPDIF code was used to simulate the interacting flames. The GRI-v3.0 was used to calculate the chemical reactions. Emission index for CO(EICO) was evaluated to quantify the CO emitted from the interacting flames. The global strain rate and equivalence ratios for each flame(ΦCH₄ and ΦH₂) were used as parameters to control the extent of interaction between two partially premixed flames. When ΦCH₄ was kept to stoichiometric condition and ΦH₂ was at rich condition, unburned H₂ species of hydrogen flame was transported to the methane flame and affected reactions related with CO formation. When ΦCH₄ increased from a stoichiometry to rich condition while ΦH₂ was kept to stoichiometric condition, EICO increased initially, had a peak value at ΦCH₄ = 1.5 and decreased gradually. This could be elucidated with an analysis for the elementary reactions related with CO formation.
