- Abstract
This paper considers a numerically simulated flow in a cylindrical liquid metal column driven by pulsed Lorentz force in a range of the modulation frequency fp of 0:05 Hz < fp < 1 Hz. The calculations were conducted with the ANSYS Fluent software package using a Large Eddy Simulation (LES) turbulence model. The pulsed case is compared with a melt flow produced by a continuously applied force. To that, the contents of turbulent kinetic energy within the melt, the rate of homogenization of the temperature field, and the relaxation time after the magnetic field has been switched off in both steady and unsteady flow regimes are considered. The results show that pulsing the Lorentz force at low frequencies can be applied to intensify the melt stirring process.
