Description

Electrohydrodynamics of droplets immersed in an immiscible carrier fluid was first explored in a pioneering paper by G. I. Taylor who formulated the weakly conducting or leaky dielectric model and predicted the steady drop shape in the small-deformation limit. Contemporary literature in electrohydrodynamic studies focuses primarily on the deformations of single droplets. On the other hand, the collective behavior of many droplets shows a wide range of surprising phenomena. In the presence of a DC electric field, a multitude of unstable, chaotic, and turbulent behaviors are observed.

In this work, we use new substances for the continuous leaky dielectric phase and discrete dielectric phase. This opens new doors of possibilities to the experiments in electrohydrodynamics, with lower threshold voltages. The lower voltage thresholds enable new electrorheology experiments to be conducted, the results of which will be reported.
