设计搭建了电场作用下燃油液滴燃烧实验装置，对比了不同电压下生物柴油液滴的形态演变、变形程度、子液滴等行为，分析了不同电压下液滴火焰形貌演变、火焰尺寸等燃烧特性及最高液滴温度变化。结果表明，电压为3 kV 和4 kV 的电场会诱发生物柴油液滴产生锥射流，其破碎生成子液滴，尺寸范围为20∼120 μm，速度基本低于2.5 m·s⁻¹；受电场对火焰和液滴的综合影响，火焰变化主要表现为高度减小、宽度增大，纵横比减小；电压为1 kV 和2 kV 的电场降低了最高液滴温度，而当电压增加至3 kV 和4 kV 时最高液滴温度增加。

An experimental setup of droplet combustion in electric field was designed and established. The droplet morphology evolution and droplet deformation of biodiesel droplet as well as its secondary droplets in electric field were investigated. The corresponding combustion characteristics including the evolution of flame morphology and the flame size were also discussed. Additionally, the variations of maximum droplet temperature were studied. It was revealed that the electric field with the applied voltage of 3 kV and 4 kV could induce the cone jet on biodiesel droplet, which generated the secondary droplets with the size range of 20∼120 μm and the majority velocity of less than 2.5 m·s⁻¹. Under the effect of electric field on flame and droplet, the flame variations mainly expressed as the decrease of flame height, the increase of flame width and the decrease of aspect ratio. The maximum droplet temperature decreased in the electric field with the applied voltage of 1 kV and 2 kV. However, the maximum droplet temperature increased when the applied voltage increased to 3 kV and 4 kV.
