Numerical simulation of 3D surfactant-covered drops in a strong electric field

The numerical literature for 3D surfactant-laden drops placed in electric fields is extremely limited due to the difficulties associated with the deforming drop surfaces, interface conditions and the multi-physics nature of the problem. Our numerical method is based on a boundary integral formulation of the Stokes equations and the leaky-dieletric model; it is able to simulate multiple drops with different viscosities covered by an insoluble surfactant; it is adaptive in time and uses special quadrature methods to deal with the singular and nearly-singular integrals that appear in the formulation. In this proceeding we will show how the method is able to maintain a high quality representation of the drops even under substantial deformations due to strong electric fields.
