摘要

在化学激波管中对RP-3航空煤油的着火特性进行了实验测量

获得了多工况下RP-3航空煤油的着火延迟时间.根据RP-3航空煤油的化学组成及物理特性

提出了由体积分数分别为0.65

0.1

0.25的正癸烷、甲苯与丙基环己烷3种组分组成的模拟替代燃料

并形成了该模拟替代燃料的化学反应详细机理.采用该化学反应详细机理对该模拟替代燃料在化学激波管中多工况下的着火特性进行了数值计算

并与实验数据进行了对比分析.结果表明:在不同压力与当量比下

RP-3航空煤油着火延迟时间的对数与着火温度的倒数呈线性关系

并且随着火温度与压力的升高以及当量比的降低

着火延迟时间逐渐缩短;同时

在各工况下采用该化学反应机理计算得到的该模拟替代燃料着火延迟时间与RP-3航空煤油着火延迟时间的实验值吻合良好.

Abstract

The ignition characteristics of RP-3 kerosene were measured in a chemical shock tube and the ignition delay times of RP-3 kerosene at various conditions were gained. According to the chemical compositions and physical properties of RP-3 kerosene

a surrogate fuel including n-decane

toluene and propyl cyclohexane(volume fraction of 0.65

0.1

0.25) was provided

and the detailed chemical reaction mechanism for this surrogate fuel was developed. The ignition characteristics of this surrogate fuel in the chemical shock tube at various conditions were simulated using this detailed chemical reaction mechanism

and the simulation results were compared with the experimental data. The results show that the correlation for the logarithm of the ignition delay time of RP-3 kerosene and the reciprocal ignition temperature is linear under different pressures and equivalence ratios

and with the increase of ignition temperature and pressure and the derease of equivalence ratio

the ignition delay time is shortened. At the same time

the ignition delay times of this surrogate fuel computed by this detailed chemical reaction mechanism under different conditions agree well with the experimental data of RP-3 kerosene.
