Advanced Engineering Materials, EarlyView.The present study investigates recycling of NiTi shape memory alloys via vacuum induction melting. An ingot was synthesized from elemental Ni and Ti and subjected to three subsequent remelting cycles. Remelting increases process durations and impurity levels and adversely affects microstructures and functional properties.

Impact of Helium ii Resonant Absorption on the Ultraviolet Background Modeled in Three Dimensions
The Astrophysical JournalWe implement a treatment of helium ii absorption and reemission into the Technicolor Dawn cosmological simulations to study its impact on the metagalactic ultraviolet background (UVB) in three dimensions.

Current Status and Challenges in Data Collection for Aerospace Coatings Deposited by Plasma Spraying
Advanced Engineering Materials, EarlyView.An innovative approach has been integrated into the GRENAT project to optimize plasma spraying and coating performance. Raw materials are accelerated and melted in the plasma generated by torches, creating coatings. Monitoring sensors collect process data which are combined with ex situ characterization data.

CFD prediction of coupled radiation heat transfer and soot production in turbulent flames [PDF]
, 1996 The mechanisms governing the formation and destruction of soot in turbulent combustion are intimately coupled to thermal radiation due to the strong dependence of sooting processes and radiative loss on temperature.

The Micro-Macro Model for Transient Radiative Transfer Simulations [PDF]
, 2014 International audienceThe micro-macro model is investigated for transient radiative transfer simulations with the discrete-ordinate method. The model decomposes the radiative intensity into its macroscopic and its mesoscopic parts.

Artist: fast radiative transfer for large-scale simulations of the epoch of reionization [PDF]
Monthly Notices of the Royal Astronomical Society, 2019 ABSTRACT We introduce the ‘Asymmetric Radiative Transfer In Shells Technique’ (artist), a new method for photon propagation on large scales that explicitly conserves photons, propagates photons at the speed of light, approximately accounts for photon directionality, and closely reproduces results of more detailed radiative transfer (RT ...
