摘要
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 sig-nal 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 in-creases.The duration of the fireball and the maximum temperature of the fireball surface decrease to a certain extent.关键词
