Abstract

Electrovortex flow emerges when the current inside conducting liquids interacts with
its self-induced magnetic field. The flow structure and strength of the flow are dictated by the
current value and the presence of an external magnetic field. We present here 3D simulations for
the electrovortex flow inside a liquid metal cylinder. The results presented reveal a typical
electrovortex structure for low currents. Higher currents induce turbulence inside the
electrovortex flow without any presence of an external magnetic field. In presence of Earth’s
magnetic field, the flow structure is affected significantly. Cyclone, tornado, and rope tornado
are observed inside the domain due to the earth’s magnetic field depending on the ratio of current
applied and the earth’s magnetic field.
