摘要

利用高速纹影摄像系统

在定容燃烧弹上对异辛烷掺混乙醇的层流预混燃烧特性进行了研究

获得了两组压力为0.1、0.5MPa

5组乙醇体积掺混比为0、0.2、0.4、0.6、0.8、1.0

初始温度为433K下的层流火焰速率。为了去除火焰面拉伸作用的影响

数据处理采用非线性方法进行推导。研究结果表明

在不同当量比条件下

异辛烷/乙醇混合燃料的层流火焰速率均随初始压力的增加而降低

随乙醇体积掺混比的增加而逐渐增大。根据一步总反应假设理论

对该实验规律进行了分析

并且计算了热力学参数、输运特性参数和总体活化能

发现了化学反应动力学因素对层流燃烧速率的变化所起的主导作用。利用Chemkin软件

对预混层流燃烧速率进行了数值模拟

结果表明

Dagaut模型对异辛烷/乙醇混合燃料的预测效果更好。另外

采用Dagaut模型

对总体反应路径和火焰面结构进行了分析

发现乙醇的替代作用是乙醇掺入后对混合燃料层流燃烧速率起促进作用的原因。
