Abstract
The work demonstrates the dynamics of a compound droplet under the combined influence of an applied electric field and shear flow. For the case of dielectric fluids, the deformation of both the inner and outer interfaces can be modulated by either variation of the permittivity contrast between the fluids or the applied electric field. The investigations for leaky dielectric fluids reveal that the ratio of electrical permittivity and conductivity between the two phases play a critical role in deciding the magnitude of deformation and orientation of the compound droplet. The electric field can be suitably applied to engender breakup of the compound
