| 中文摘要 | 航空煤油火焰传播特性对航空动力装置的研发与设计均具有重要意义。本文在液体燃料对冲火焰实验台上,使用相位多普勒粒子分析仪(PDPA)在较宽的当量比范围内,测量了三种煤油表征燃料与空气掺混气的层流火焰传播速度。在标准大气压下,初温378 K时正癸烷、甲基环己烷和初温388 K时甲苯与空气预混气燃烧时能够达到的最大火焰传播速度为64.2 cm/s、58.3 cm/s和52.4 cm/s。在实验数据的基础上,进一步采用Chemkin软件对预混火焰进行了动力学分析,探讨了造成三种燃料火焰传播性质差异的动力学原因。; The flame propagation characteristics of aviation kerosene are of important significance for the development and design of aerospace power device.The counterflow twin-flame test-bed suitable for liquid fuels and Phase Doppler Particle Analyzer(PDPA) were used,and in a wide range of equivalence ratios,the laminar flame speeds of n-decane,methylcyclohexane,toluene which are typically alternative fuels of kerosene were obtained.Under the standard pressure,as the initial temperature of 378 K,the maximum of flame speeds of n-decane/air,methylcyclohexane/air are 64.2cm/s,58.3 cm/s;as the initial temperature of 388 K,the maximum of flame speeds of benzene/air is52.4 cm/s.Based on the experimental data,the kinetic analysis on premixed flame were implemented using Chemkin software,and the reasons causing the difference of flame propagation characteristics of three fuels were further analyzed. |
