FLUID-FLOW AND FREE-SURFACE PHENOMENA IN ROTARY ELECTROMAGNETIC STIRRING OF A METALLIC MELT

Flow velocities and free surface deformation in an electromagnetically stirred Wood's metal system were investigated using both computationa l and experimental methods. Local flow velocities were measured using an electromagnetic Vives probe. Computations were performed using a co mmercial computational fluid dynamics package modified with user subro utines to take into account the electromagnetic forces induced by the rotary electromagnetic stirrer. Results of the two methods were found to be in good agreement for the flow velocities, total free surface de formation, and the time scale to reach the final flow velocity and fin al shape of the free surface. The presented paper is reporting the res ults of the second part of the author's previously reported research.
