To study water droplet dynamic behavior in the silicone oil under a uniform DC electric field, a visual experiment system is set up. Two parallel plates are placed to form a uniform DC electric field. Results show when the electric field intensity is less than 2.33 kV/cm, with the increase of the electric field intensity, the droplet stretches in the vertical direction. The droplet detaches from the lower plate at 2.45 kV/cm. The droplet breaks into two daughter droplets at 3.67 kV/cm. Two daughter droplets coalesce at 4.67 kV/cm. A liquid bridge is formed at 4.93 kV/cm.

均匀直流电场中小液滴动态行为的实验研究

为了研究均匀直流电场作用下硅油中的水滴动态行为，建立了视觉实验系统。放置两个平行板以形成均匀的直流电场。结果表明，当电场强度小于2.33 kV / cm时，随着电场强度的增加，液滴沿垂直方向拉伸。液滴以2.45 kV / cm的速度从下板上脱落。液滴以3.67 kV / cm的速度分裂为两个子液滴。两个子液滴在4.67 kV / cm处聚结。以4.93kV / cm形成液桥。
