A high-order discontinuous Galerkin Finite Element solver is developed for solving
electro-fluid-dynamics problems. The solver is employed to perform numerical simulations of
deformation of a droplet suspended in another immiscible liquid by applying steady and
oscillatory electric fields. The level set method is adopted to represent the common interface
of the droplet and surrounding medium. Electrostatics equation with a jump in the dielectric
property at the interface is solved to find the electric field distribution. The incompressible
Navier-Stokes equations including the surface tension force are solved to find the flow field.
The Electrostatics and Navier-Stokes equations are coupled through changes in the geometry
because of the deformation of the droplet and the dielectrophoretic body force, which is
present at the interface.
