A numerical investigation was conducted to simulate the transport of charged molecules in a flow system of two immiscible fluids and an electrical field orthogonal to the flow direction. A finite element based method was implemented using COMSOL Multiphysics 3.5a to solve the multiphase transport in rectangular type geometries. The Level set method was employed to explicitly describe the location of the moving fluid interface. Solutions to the Navier-Stokes equations coupled with the Level set and electrophoretic transport relations were obtained for typical proteins encountered in two phase extraction systems. System properties were modeled to be consistent with a polyethylene glycol -- dextran -- water solution at the macroscopic scale.
