本文采用基于特征值分析的骨架机理简化方法,对于航空煤油替代燃料正癸烷(118组分527反应)和正丙基环己烷(106组分382反应)氧化反应机理进行了简化,分别得到68组分302反应和67组分250反应骨架机理。采用骨架机理进行了着火延迟和火焰传播速度动力学模拟,并与详细机理计算结果进行了对比,结果表明,骨架机理具有较高的计算精度,该方法对于高碳氢燃料的详细机理简化具有较好的效果。 In this paper, the skeleton mechanism simplification method based on eigenvalue analysis is used to simplify the oxidation reaction mechanism of aviation kerosene for n-decane (118 component 527 reaction) and n-propylcyclohexane (106 component 382 reaction) to obtain 68 Component 302 reaction and 67 component 250 react with the backbone mechanism. The kinetics of flame retardation and propagation velocity of flame were simulated by the skeleton mechanism and compared with the results of the detailed mechanism calculation. The results show that the skeleton mechanism has high calculation accuracy. This method is more effective for the detailed mechanism simplification of high-carbon fuels Good results.
