Abstract
A numerical model for simulating electro-vortical flows in OpenFOAM is developed. Electric potential and current are solved in coupled solid-liquid conductors by a parent-child mesh technique. The magnetic field is computed using a combination of Biot-Savart's law and induction equation. Further, a deflated PCG solver for the electric potential is implemented. Finally, a performance analysis is presented and the solver is validated against several test cases.
