Experiment on the oxidation and ignition delay characteristics of RP-3 kerosene/oxygen
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.
