Numerical modeling of coupled electromagnetic and thermal processes in the zone induction heating system for metal billets

Electrical engineering & Electromechanics
Introduction. For many modern manufacturing processes, induction heating provides an attractive combination of speed, consistency and control. Multi-inductor (zone) systems with continuous billets feed are the most promising, which keep the billet cross ...

Robust Spot Melting by 3D Spot Arrangements in Electron Beam Powder Bed Fusion

Advanced Engineering Materials, EarlyView.
This work proposes an approach to replace separately melted contours for spot melting in electron beam powder fusion. Adapting the spot arrangements close to the contour combined with stacking yields a comparable surface quality without the inherent challenges of separate contours, as demonstrated, by electron optical images and roughness measurements.

Heat sources and melting in subduction zones [PDF]

Journal of Geophysical Research: Solid Earth, 1997
In order to understand the mechanism of melt generation and the origin of high heat flow in subduction zones, a series of numerical models of the thermal and flow structures in the mantle have been tested in two‐dimensional boxes with an inclined subducting slab of constant velocity.
