Evolution of silicone oil droplets over time in different modes (viscosity ratio λ = 1.4, initial diameter a=3.05 mm). (a) The deformation evolution process of droplets in Taylor deformation mode with E0 = 2 kV/cm. (b) The deformation evolution process of the drop in the typical oblique rotation mode with E0 = 3.25 kV/cm. (c) The evolution process of drop deformation in periodic oscillation mode with E0 = 3.9 kV/cm. (d) The deformation evolution process of the drop in the fracture mode with E0 = 4.5 kV/cm.
