- Abstract
This article examines the influence of an induction coil position and configuration on the fluid flow and heat transfer characteristics in electromagnetic (EM) solidification processes. The mutual inductance technique was used to solve for the EM field, whereas a dual-zone model was used to describe the flow in the two-phase "mushy" region, and accounts for damping of the flow due to grain growth within the suspended particle region. Simulations were performed for a A319 aluminum alloy within a laboratory-scale casting apparatus surrounded by a six turn coil for three configurations and three locations with respect to the melt. It was found that the coil arrangement had only a small effect on the flow structure and velocities in comparison with the coil position. The implications with regard to solidification behavior are discussed.
