Due to its molecular polarity, a water droplet suspended in a dielectric medium experiences a force under the influence of an electric field. However, unlike a charged rigid particle, a water droplet undergoes a significant deformation due to its liquid state. Thus, the dynamic behavior of the water droplet cannot be fully analyzed without accounting for the interaction between the electric and fluid fields. In an effort to broaden our understanding of this phenomenon, a parallel plate electrode system was constructed inside a glass chamber. A water droplet was suspended in the glass chamber filled with insulated oil. After applying a high voltage across the plates, the droplet motion was recorded with a camera and analyzed using an image processing program. The effects of several parameters including, droplet size, droplet conductivity, and initial droplet position were investigated. Results obtained from this investigation help gain a better understanding of the droplet deformation and breakup mechanisms spanning several fields, some of which include oil-water separation, electrocoalescence, and electrospraying.
