本文基于热流量法搭建了层流火焰速度测量平台,通过测量甲烷的绝热层流火焰速度对平台的可靠性进行了验证.然后运用热流量法对15%H2-15%CO-70%N2和12%H2-19%CO-1 3.2%CO2-5.8%CH4-50%N2两种组分合成气的绝热层流火焰速度进行了精确测量,并通过Chemkin 4.1软件采用GRI-Mech 3.0,USC Mech Ⅱ和Davis H2/CO三种机理对试验工况进行了计算.实验数据与计算结果基本一致,尤其与GRI-Mech 3.0机理的计算结果较好地吻合.本文还对实验误差进行了误差分析,对两种合成气的平均测量误差分别达到1.107 cm/s和0.88 cm/s.
