A Numerical Simulation of the Magnetically Driven Flows in a Square Container Using the Delayed Detached Eddy Simulation

The isothermal unsteady turbulent flow driven by a rotating magnetic field in a square container at Taylor number 1 x 10(6) was investigated numerically using in-house CFD code. The quasi isothermal electrically conducting fluid was exposed by the higher intensity of the magnetic induction, and consequently, the induced flow turned up to be turbulent at higher Reynolds or Taylor numbers. As a turbulent approach, the Delayed Detached Eddy Simulation model was successfully applied. The magnetic force calculation assumed the low frequency/low induction conditions. The effect of the rotating magnetic field gives rise to the time-independent magnetic body force, computed via the electrical potential equation and Ohm's law and the time-dependent part that is neglected due to the low-interaction parameter. The characteristic results provided numerically were time-averaged velocity fields, turbulent quantities, vortex flow structures etc.
