| 摘 要： | 介绍一种基于燃料氧化反应动力学计算的单区模型,该模型由一维空间的质量守恒方程、动量守恒方程、能量守恒方程和气体状态方程等气相化学反应动力学控制方程所组成。采用该模型并利用二甲醚氧化的详细化学反应动力学机理,对二甲醚燃料在柴油机上的均质压缩燃烧HCCI进行了模拟计算和试验研究。计算结果与试验结果比较表明,该模型对HCCI燃烧的着火始点预测很好。

| Abstract: | A single-zone model based on calculation of chemical kinetics of fuel oxidation is introduced. The model includes mass conservation equation, momentum conservation equation, energy conservation equation and gas state equation. By using the model and detailed chemical kinetics of Dimethyl Ether(DME)oxidation, HCCI combustion of DME in a diesel engine is numerically simulated and tested. Comparisons between calculated results and experimental results show that the model can accurately predict start of auto-ignition of HCCI combustion. |
