摘要:
在一台快速压缩机上进行了正癸烷在当量比0.46~1.50、压力0.7~1.5,MPa、温度范围600~750,K 条件 下的中低温着火特性研究.结果表明,正癸烷具有明显的两阶段着火特性;正癸烷着火延迟均随着温度、压力的 升高而减小;不同当量比和氧气体积分数条件下的研究表明,正癸烷低温阶段着火延迟更依赖于燃料体积分数而 对氧体积分数不敏感.采用两个正癸烷机理进行了模拟研究并与实验结果进行了对比,并通过敏感性分析研究了 特定基元反应在控制正癸烷着火过程中的作用.
Abstract:
This paper presents the ignition delay data for n-decane with a heated rapid compression machine at the equivalence ratio ranging from 0.46 to 1.50,the compressed pressure corresponding to 0.7—1.5,MPa,and the compressed temperature varying from 600,K to 750,K.The experimental results show that n-decane exhibits obvious two-stage ignition characteristics,and the ignition delay time drops with the increase of either the compressed pressure or the compressed temperature.The ignition delay time is more sensitive to the change of fuel concentration but is relatively independent with oxygen percentage under low-to-intermediate temperature conditions. Besides, the performance of two n-dedane mechanisms is estimated by comparing the modeling result with the experimental data.Sensitivity analysis is then conducted to understand the role of specific reactions in controlling ndecane autoignition.
