The image shows the magnetic fields and electric current densities in an idealized electromagnetic casting process. An electromagnetic field is used for heating, stirring and confinement of the liquid and solid metal. By calculating these EM field values, we can study the velocity profile of the liquid metal and the position of the liquid metal/solid metal interface over a range of process parameters. The use of massively parallel computers allows great refinement in the mesh, particularly in the boundary regions where the values EM fields are undergoing large changes in relatively small distances. These studies will aid in the control of existing EM casting processes and also help in the design of future casters. This work was presented at the Minerals, Metals and Materials Society Annual Meeting in February, 1996 in Anaheim, CA.
About the image
In this example, the experimental volume is a cylinder. The images show an "unwrapping" of the cylinder.- The top plane shows the electric current density (Amps/centimeter^2),
- color represents the real component (data range -0.5489 to -0.0055),
- height represents the imaginary component (data range -1.3838 to -0.0004)
- The middle plane vector surface shows
the magnetic field of the cylinder in the vertical direction,
- vector x represents the real component
(data range -1.2876 to 1.9139),
- vector y represents the imaginary component (data range -0.2785 to 0.0563)
- The bottom plane shows the magnetic field of the cylinder in the
radial direction,
- color represents the real component (data range -1.6148 to 1.6148),
- height represents the imaginary component (data range -0.0634 to 0.0634)
