Monolithic simulation of convection-coupled phase-change - verification and reproducibility

, 2018
Phase interfaces in melting and solidification processes are strongly affected by the presence of convection in the liquid. One way of modeling their transient evolution is to couple an incompressible flow model to an energy balance in enthalpy ...

Understanding hydrogen-induced pore formation and release in Al-Cu alloy L-PBF process with auxiliary preheating

Materials & Design
Laser powder bed fusion (L-PBF) enables the fabrication of high-strength aluminum alloys, but hydrogen-induced porosity remains a major challenge due to the large solubility gap between liquid and solid phases.

Physicochemical characterization and thermal behavior of guanabana (Annona muricata) seed “almond” oil

Grasas y Aceites, 2010
In this work some physicochemical properties and the thermal behavior and stability of sour sop or guanabana (Annona muricata) seed “almond” oil were studied by means of chemical, DSC and TG analysis. The results showed that the almond has 2.5% ash, 17.9%
