Induction heating for pendent-drop melt extraction (PDME) from a metallic sheet is simulated and optimized. This numerical study aims at concentrating dissipated powers on the lower edge of the metallic sheet so that multi-extraction of fine fibers from the wide metallic drop is realized. The solutions on the electromagnetic field are obtained numerically by three-dimensional (3D) modeling based on Finite Element Method (FEM) using ANSOFT Maxwell software, then verified experimentally by lab-scale tests. Subjects to variation are (1) the extension of the substrate (extraction wheel) in both directions parallel and perpendicular to the inductor, (2) the protrusion depth of the edge below the lower face of the inductor and (3) the shape of the inductor. The numerical simulations suggest that the vertical position of the inductor has to be significantly higher than that in Reference 1 in order to increase the efficiency of the process.
