Electro-vortex flow in a cylindrical container
Liu, K.; Li, B. W.; Stefani, F.; Weber, N.; Weier, T.;
In a cylindrical container filled with the eutectic alloy GaInSn, an electro-vortex flow (EVF) is caused by the interaction of a non-uniform current with the magnetic field that it generates. In this paper, we investigate the EVF numerically and experimentally. First, based on a solver by Weber, we develop a more advanced one, in which the effect of Joule heating is considered. The magnetic field, which is the combination of the current induced magnetic field and the external geomagnetic field, is also taken into account. For getting a higher computational efficiency, the so-called parent-child mesh technique is applied in OpenFOAM. Second, we conduct an experiment corresponding to the numerical simulation, in which Ultrasound Doppler Velocimetry (UDV) is applied for flow measurements. The results of the experiment are in good agreement with those of the simulation.
