| 中文摘要: |
| 研究目的是优化氢气/空气简化反应机理的系数,使得简化机理在一定的误差范围内,能代替详细机理。通过计算氢气/空气详细反应机理得到的组分浓度作为遗传算法的适应度目标,对简化机理进行优化。结果显示,优化后的简化机理不仅在在计算组分浓度,而且在层流预混火焰速度和组分时空分布方面,更加接近详细机理所能达到的计算结果,比优化之前的简化反应机理计算结果更加准确 |
| 英文摘要: |
| This study aimed at optimizing the hydrogen/air simplification reaction mechanism’s coefficient,so that the simplified mechanism at a certain range of error,can replace the detailed mechanism.We obtain the species concentration through the computation hydrogen/air detailed reaction mechanism,and take the species concentration as the genetic algorithm goal,to optimize the simplified mechanism.The results showe that the optimized simplified mechanism not only in computation the species concentration,but also in the laminar premixed flame speed and the temporal and spatial distribution of species aspect,is more accurate than unoptimized simplification reaction mechanism computed result. |
