摘 要: 利用纹影高速摄影技术,在定容燃烧弹内研究不同过量空气系数、不同成分可燃混合气(H2,H2+CO,75%含水酒精,85%含水酒精,95%含水酒精,75%含水酒精掺加不同比例的H2)的层流燃烧特性参数。结果表明:混合气的层流传播速度随过量空气系数的增大而减小,随掺氢比的增加而增加;含水酒精的马克斯坦长度随过量空气系数的增加而增加,且掺氢能降低含水酒精的马克斯坦长度。
关 键 词: 能源化学;含水酒精;层流传播速度;马克斯坦长度

Abstract: The laminar combustion characteristics of combustible gas mixture (H2, H2+CO, 75% aqueous alcohol, 85% aqueous alcohol, 95% aqueous alcohol, 75% aqueous alcohol mixing different proportions of H2) were studied at different excess air ratio by using high-speed schlieren photography technique in a constant volume combustion bomb. The results show that laminar glow velocity decreases with the increase of excess air ratio. Increasing of hydrogen fraction will increase laminar burning velocity. Markstein length of aqueous alcohol increases with the increase of excess air ratio and decreases with the increase of hydrogen fraction.
Key words: energy chemistry; aqueous alcohol; laminar glow velocity; Markstein length
