摘要:
1-戊烯是国产93 号汽油的重要烯烃组成成分,通过定容弹燃烧实验系统测量了1-戊烯在初始压力 0.1,MPa 和0.3,MPa,初始温度350,K 和450,K、当量比从0.5~1.6 的层流火焰传播速度,结果表明初始压力的升 高对1-戊烯的层流火焰传播速度有抑制作用;而初始温度的升高则对其有促进作用;随着当量比的增大,层流火 焰传播速度先增大,在当量比为1.1 处取得最大值,而后随之下降.对比1-戊烯反应机理计算结果发现,机理计 算结果无法较好地与实验结果吻合,并且机理过于庞大,无法应用于实际CFD计算.
Abstract:
1-pentene is the main composition of alkene in gasoline 93,and its laminar flame propagation speed was measured by the constant volume combustion bomb at the initial temperatures of 350,K and 450,K,the initial pressures of 0.1,MPa and 0.3,MPa,and the equivalence ratios from 0.5 to 1.6,respectively.The results show that the laminar flame propagation speed of 1-pentene/air would be inhibited with the increase of initial pressure but promoted with the increase of initial temperature.With the increase of equivalence ratio,the laminar flame propagation speed increases first,and reaches the maximum at φ=1.1,and then decreases in the fuel-rich condition.In addition,two detail mechanisms of 1-pentene were employed to calculate the laminar flame propagation speed, and the result shows that neither of them could perform good predictions in all the experimental conditions. Moreover,the numbers of species and reactions are too large for CFD simulation.
