摘要
采用敏感性分析的方法对以 GRI 3.0 数据库和 Gear 算法为基础的天然气再燃脱硝机理模拟进行简化。从简化后的反应方程式中可以揭示发生脱硝的主要影响自由基。通过选择不同的简化机理方案比较,得出选择敏感性系数绝对值排列在前面 200 位的反应替代325 个总模型反应体系基本没有误差,在考虑湍流相结合或在温度超过 1 450 K 的模拟中,采用敏感性系数绝对值排列在前 150 或 100个反应能代替总模型。
Sensitivity analysis has been used to simplify the kinetic model based on GRI 3.0 data bank and Gear algorithm. The main radicals that influence the efficiency greatly is found from the simplified model. By comparing different simplified models, it is found that the 200 reactions model based on the sensitivity coefficient can replace the detail model because little inaccuracy, it is found that the 150 reactions or 100 reactions model based on the sensitivity coefficient can used in computation when considering turbulent or in the condition of temperature above 1450K.
