发展准确可靠的航空煤油燃烧反应动力学模型，对于优化燃烧室的参数设计以及改进航空发动机性能将起到重要作用。航空煤油反应动力学模型由于输入参数众多、相互耦合机制复杂、需验证的工况范围广等诸多原因，当前模型预测值具有显著的不确定性，尚难以满足实际应用的需求。本项目拟发展新的实验设计方法，寻找可有效约束航空煤油燃烧反应动力学模型参数或可降低发动机真实工况条件下模型预测误差的基础燃烧实验条件和目标，以减少实验测量的盲目性；发展反向不确定性分析方法以提高对大分子燃料反应动力学模型优化问题的处理能力；在此基础上构建航空煤油关键组分的燃烧反应动力学优化模型，为进一步发展宽范围下具有更强预测能力的航空煤油反应动力学模型提供支持。

The development of a predictive combustion kinetic model for jet fuels plays a key role in the parameter optimization for combustion chamber design, as well as in the performance improvement for aviation engines. Due to vast of model input parameters, their coupling effects, and the large temperature or pressure ranges needed to be validated, the current combustion kinetic models for jet fuels are far from perfect. This project is to develop new experimental design methods, to find the most useful conditions or targets for the constraint of the model parameters and reduce the predictions at engine operating conditions; to improve the ability of the inverse uncertainty quantification algorithm towards the optimization problems for the fuels of large molecules; to develop an optimized kinetic model for the key species in the jet fuel, which will support the improvement of a robust predictive jet fuel kinetic model.
