Surrogate fuels are useful for computational fluid dynamics (CFD) simulations. However, there are two main challenges in surrogate fuel: defining an appropriate surrogate and designing compact and reliable kinetic models. Many works of defining an appropriate surrogate have been done in our previous work. In this study, we focus on obtaining compact and reliable kinetic models for jet surrogate fuels. A detailed mechanism was developed by combining n-dodecane, 2,5-dimethylhexane and toluene sub-mechanisms with AramcoMech 2.0 C₀–C₄ mechanism to mimic the combustion properties of three representative jet fuels. Extensive validation of the component mechanisms in surrogate is performed using abundant experimental data sets. Thereafter, various combustion properties of three jet fuels like ignition delay times, species concentrations in flow reactor and laminar flame speeds are simulated by using this surrogate kinetic mechanism and previous surrogate formulations. The simulations are compared with other well-known surrogate models and a wide range of experimental data. The comparisons show that the developed mechanism is substantially improved prediction accuracy of most considered combustion properties for different jet fuels in a wide range of conditions.

替代燃料可用于计算流体动力学（CFD）模拟。但是，代用燃料存在两个主要挑战：定义适当的代用燃料和设计紧凑而可靠的动力学模型。在我们以前的工作中，已经完成了许多定义适当代理的工作。在这项研究中，我们着重于为喷气替代燃料获得紧凑而可靠的动力学模型。通过将正十二烷，2,5-二甲基己烷和甲苯的子机理与AramcoMech 2.0 C ₀ –C ₄结合起来，开发了详细的机理。模拟三种代表性喷气燃料燃烧特性的机理。使用大量的实验数据集对替代机制的广泛验证。此后，通过使用这种替代动力学机制和先前的替代配方，模拟了三种喷气燃料的各种燃烧特性，例如点火延迟时间，流动反应器中的物质浓度和层流火焰速度。将模拟与其他众所周知的替代模型和广泛的实验数据进行了比较。比较结果表明，所开发的机理大大提高了在各种条件下对各种喷气燃料而言最受关注的燃烧特性的预测精度。
