摘要:
为探究铝粉粒径对含铝煤油凝胶燃料激波诱导点火的影响规律，利用纹影法与阴影法对铝粉粒径为1.20、7.05 μm及23.63 μm的含铝煤油凝胶燃料在激波管内的点火过程进行了观察。通过分析测得的压力信号和铝粉燃烧产物光信号，对比了含不同粒径铝粉的凝胶燃料在激波诱导作用下的点火和燃烧特性。结果表明：随着铝粉粒径的增大，凝胶燃料雾化后云团的均匀性变差，点火延迟时间也随之增加，火球的持续时间以及火球表面的最高温度均有一定程度的减小。
Abstract:
In order to investigate the influence of particle size of aluminum powder on shock wave induced ignition of aluminum-kerosene gel fuel, schlieren method and hadowgraph method were used to observe the ignition process of aluminum-kerosene gel fuel with particle sizes of aluminum powder of 1.20, 7.05 μm and 23.63 μm in shock tube. The ignition and combustion characteristics of gel fuels under shock wave induction were compared by the measured pressure signal and the optical signal of aluminum powder combustion products. The results show that the uniformity of the atomization cloud of the gel fuel deteriorates with the increase of the particle size of the aluminum powder, the ignition delay also increases. The duration of the fireball and the maximum temperature of the fireball surface decrease to a certain extent.
