摘要

利用双膜化学激波管实验装置反射激波方法测量了丙烯/氧气/氮气混合气在温度范围为1 650～1 900 K、压力为0.1 MPa下的着火滞燃期.通过对理想激波管内流动状态分析

给出了合适的着火滞燃期定义.实验结果表明:随着初始温度的增加

丙烯/氧气/氮气混合气着火滞燃期缩短

着火滞燃期的对数与温度的倒数成正比

入射激波强度与着火滞燃期的对数成反比; 高温条件下

混合气的着火滞燃期随着初始压力的增加而增加

随浓度的增加而缩短; 利用多元线性回归方法拟合了C

着火滞燃期的Arrhenius型关系式

计算结果与文献中的实验数据具有很好的吻合性.

Abstract

Ignition delay times were measured for propene/oxygen/nitrogen mixtures behind reflected shock waves in a double diaphragm chemical shock tube in the range of 1 650-1 900 K and at 0.1 MPa. An appropriate definition of ignition delay time was proposed based on an analysis of the flow condition in an ideal shock tube. The experiment results show that the ignition delay times of the mixtures decreased with the increase in initial temperature. The logarithmic value of the ignition delay times was proportional to the reciprocal of temperature and inversely proportional to incident shock intensity. Under high temperature conditions

the ignition delay times increased with the increase in initial pressure and decreased with the increase in the concentration of propene in the mixtures. An Arrhenius-type correlation equation for the ignition delay time of propene/oxygen/nitrogen mixtures was developed

and its calculation results agree well with the data in literature.
