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

Popis výsledku v původním jazyce

The isothermal unsteady turbulence flow driven by a rotating magnetic field in a square container has been investigated numerically using in house CFD code. The quasi isothermal electrically conducting fluid is exposed by the higher intensity of the magnetic induction and consequently, the induced flow turned up to be turbulent at higher Reynolds or Taylor number. As a turbulent approach, the Delayed Detached Eddy Simulation model has been successfully applied. For magnetic force calculation, the low frequency / low induction has been assumed. 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 tothe low interaction parameter. The flow results in the square container has been compared to the results of the cylindrical container and several differences could be identified.
