摘　　要：针对传统化学反应机理简化方法无法兼顾精度和计算量的问题,提出了耦合化学反应机理简化和优化方法(CROM).应用CROM成功实现了对RP-3航空煤油3组分替代燃料详细化学反应机理的简化和优化,得到包含47组分、94反应的优化机理.采用优化机理,数值模拟了RP-3航空煤油在激波管和对冲火焰装置中的燃烧过程,并将模拟结果与文献实验值和文献计算值进行对比验证.结果表明,该优化机理能够准确预测RP-3航空煤油的点火延迟时间和火焰传播速度,且比文献的化学反应机理规模更小、计算效率更高,具有较高的工程应用价值.Since traditional chemical mechanism reduction method could not take in account of both accuracy and computation amount,CROM（Combined Reduction and Optimization Method）was proposed to solve this problem.CROM was successfully executed to develop 47 species and 94 reactions for the optimized mechanism for three-component RP-3 aviation kerosene surrogate fuel.Combustion in shock tube and counterflow flame was simulated using the optimized mechanism,and the results were compared with the experimental and calculated value in the literature.The results show that the optimized mechanism can accurately predict the ignition delay time and laminar flame speed.The optimized mechanism owns less scheme and high computation efficiency,and is of great engineering application value.
