Summary:Measurements and modeling of flow characteristics are presented for turbulent flow subjected to current-magnetic field interaction in 208 kA end to end prebaked cells. The numerical calculations of incompressible turbulent flow have been carried out by solving full time -averaged Navier-Stokes equation using finite difference method. The k-epsilon turbulence model is modified to account for near wall function. In this part, the electromagnetic force is introduced in the governing equations as source term. Velocity measurements in the metal pad were established using iron rod method. The calculated and measured velocities showed a good agreement and the model can be used to predict the velocity profiles inside the molten melt regions at different operating conditions.
