Electrohydrodynamic deformation and oscillatory dynamics of a neutrally buoyant droplet
Abstract
This study investigates the electrohydrodynamic deformation of dielectric liquid droplet exposed to a uniform electric field. Experiments are performed using a two-phase system comprising a silicone oil droplet dispersed in castor oil as the bulk. The droplet behaviors, including deformation, flattening, oscillation, and rotation, are analyzed across a range of electric field strengths using shadow imaging technique. For electric field strengths ranging from Eo = 4.5 to 5.75 kV/cm, the silicone oil droplet initially deforms into an oblate shape, with their axes tilting relative to the direction of the applied field. At lower field intensities, i.e., Eo
