摘要：

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. © 2023 Science Press. All rights reserved.
