| 摘 要： | 利用激波管实验装置由反射激波点火,在点火温度1 164～1 566 K,点火压力1.03～1.99 atm,燃料浓度为1.0%,当量比为1.0的条件下,用光谱单色仪、光电倍增管、压力传感器和示波器等组成测试系统,测量了甲基环己烷燃烧过程中主要中间产物OH,CH和C2自由基特征光辐射随时间的连续变化,并测得了甲基环己烷/氧气/氩气的点火延迟时间。通过对测量结果的分析,初步认识了甲基环己烷燃烧反应中几个主要中间产物的光辐射特性及其反映出的甲基环己烷燃烧反应特性。实验所测点火延迟时间与已报道的实验结果和燃烧反应机理预测结果符合较好。本文实验结果为构建和验证甲基环己烷燃烧反应机理提供了实验依据。

| Abstract: | Using a measurement system consisting of monochromators,photomultiplier tubes,piezoelectric pressure sensors and a digital oscilloscope,characteristic emissions of intermediate products OH,CH and C2 produced in the combustion reaction of methylcyclohexane were measured behind reflected shock waves in a shock tube,and ignition delay times of methylcyclohexane/oxygen/argon were acquired.Experimental conditions cover temperatures from 1 164 to 1 566 K,pressures from 1.03 to 1.99 atm,a fuel concentration of 1.0... |
