Electrohydrodynamic interactions of drop pairs
share
We present three-dimensional simulations of the dynamics of a drop pair in an applied uniform DC electric field. The numerical method is based on a boundary integral formulation of the leaky dielectric model. We apply the method to explore the electrohydrodynamic interactions between two identical drops with arbitrary orientation of the their line of centers relative to the applied field direction. Our results show complex dynamics depending on the conductivities and permittivities of the drops and suspending fluids, and the drop pair alignment with the applied electric field.
