On the formation of microstructural gradients in a nickel-base superalloy during electron beam melting

open access: yesMaterials & Design, 2018
Electron beam melting (EBM) is one of the most widely used additive manufacturing (AM) methods for metallic components and has demonstrated great potential to fabricate high-end components in the aerospace and energy industries.

The one-dimensional Stefan problem with non-Fourier heat conduction

open access: yes, 2019
We investigate the one-dimensional growth of a solid into a liquid bath, starting from a small crystal, using the Guyer-Krumhansl and Maxwell-Cattaneo models of heat conduction. By breaking the solidification process into the relevant time regimes we are

Comparative CFD simulations of a hydrogen fire scenario [PDF]

open access: yes, 2017
Hydrogen leakage and fire ignition and propagation are safety concerns in several industrial plants. In a nuclear fusion power plants the separation of hydrogen and tritium takes place in different steps, among which one or more electrolyzers are ...
