| 摘 要： | 引入数值模拟精度的定义,采用两组分参比油模拟了HCCI发动机点火过程,对Youngchul Ra和Rolf D. Reitz提出的正庚烷与异辛烷氧化过程进行敏感性分析及优化处理,对H.J.Curran的详细反应机理进行数值验证,在验证范围(初始温度530~600 K,当量比0.3~0.8,压缩比12.5~28)的大部分区域内,优化后简化模型的数值模拟结果满足一级精度。利用HCCI发动机的三维CFD耦合化学动力学模型,模拟缸内燃烧流动过程,得到缸内压力及中间产物和燃烧相位的关系,计算结果与试验结果吻合较好。

| Abstract: | The definition of numerical simulation accuracy was introduced and the ignition process of HCCI engine was simulated with the two-component PRF.For the oxidation process of n-heptane and isooctane,which was put forward by Youngchul Ra and Rolf D.Reitz,the sensitivity analysis and optimization were carried out.The H.J.Curran detailed reaction mechanism was validated.In the most regions of 530-600 K initial temperature,0.3-0.8 equivalence ratio and 12.5-28 compression ratio validation range,the numerical simu... |
