利用纹影高速摄影技术,在定容燃烧弹内模拟研究了不同过量空气系数、不同成分含水乙醇重整混合气的层流燃烧特性参数,并利用CHEMKIN软件模拟计算了重整混合气的绝热火焰温度。结果表明,模拟重整混合气的层流传播速度随过量空气系数的增大而减小,随混合气中氢含量比例的增加而增加;重整混合气燃烧会降低NO、CO的排放。
In this paper, we simulate the laminar flow combustion parameters of air-reforming mixed gas with different excess air ratio and different composition of ethanol in constant volume combustion bomb by using the high-speed photography technology. And simulate the adiabatic flame of reformed mixture with CHEMKIN software temperature. The results show that laminar flow velocity of simulated reformed gas decreases with the increase of excess air coefficient and increases with the increase of hydrogen content in the mixed gas. Combustion of reformed mixture can reduce the emission of NO and CO.
