摘要
在流动管反应器中对当量比分别为0.5、1.0、2.0、温度范围为550～1 200K、压力分别为0.1、3.0 MPa条件下RP-3航空煤油/O2的氧化特性进行了试验测试.结果表明:当量比由0.5增加到2.0时,RP-3航空煤油/O2氧化过程中各组分生成的起始温度以及出现摩尔分数峰值时的温度均升高;压力由0.1 MPa升高到3.0 MPa时,RP-3航空煤油/O2氧化过程中各组分生成的起始温度以及出现摩尔分数峰值时的温度均降低,烷烃的摩尔分数峰值升高,而烯烃的摩尔分数峰值则降低.同时,在激波管中对当量比分别为0.8、3.5、压力分别为0.2、1.0、5.0 MPa、温度范围为950～1 500 K条件下RP-3航空煤油/O2的着火延迟特性进行了试验测试.结果表明,RP-3航空煤油/O2的着火延迟时间随压力与温度的升高、当量比由3.5减小到0.8时逐渐缩短.
Abstract
The oxidation characteristics of RP-3 kerosene/O2 were experimentally tested in the flow reactor under the conditions of the equivalence ratios of 0.5,1.0 and 2.0,the temperature range of 550-1 200 K,the pressure of 0.1,3.0 MPa.The results showed that,with the increase of equivalent ratio from 0.5 to 2.0,the starting temperature of each species formation and the corresponding temperature of the peak mole fraction of each species increased.With the increase of pressure from 0.1 MPa to 3.0 MPa,the starting temperature of each species formation and the corresponding temperature of the peak mole fraction of each species decreased,and the peak mole fraction of alkanes increased while that of alkenes decreased.Meanwhile,the ignition delay characteristics of RP-3 kerosene/O2 were experimentally tested in the shock tube under the conditions of the equivalent ratios of 0.8,and 3.5,the pressure of 0.2,1.0,and 5.0 MPa,the temperature range of 950-1 500 K.The results showed that,with the increase of the pressure and temperature or the decrease of equivalent ratio from 3.5 to 0.8,the ignition delay time of RP-3 kerosene/O2 was shortened.
