Boundary Condition for the Electric Field in Earth's Core Models With Conducting Boundaries
Geophysical Research LettersThe Earth's core flows are governed by magnetohydrodynamic equations, where boundary conditions determine how the electric field in the liquid core relates to that in the conducting boundaries.

Unified slip boundary condition for fluid flows
Physical Review E, 2016 Determining the correct matching boundary condition is fundamental to our understanding of several everyday problems. Despite over a century of scientific work, existing velocity boundary conditions are unable to consistently explain and capture the complete physics associated with certain common but complex problems, such as moving contact lines and ...

Karl Popper and the Mechanisms of Hydrogen Embrittlement
Advanced Engineering Materials, EarlyView.Representation of the beginning of loss of ductility rather than embrittlement. Small concentrations of hydrogen in a diffusible form within iron are well‐established to harm the mechanical integrity of steels. There are theories that attempt to explain the pernicious role of hydrogen.

Advanced Engineering Materials, EarlyView.Copper‐based composites enhanced with carbon feature convenient mechanical properties and favorable electric conductivity. Processing via deformation and thermomechanical treatments can introduce advantageous microstructures further enhancing their performance. Herein, copper–graphene powder‐based composites are directly consolidated via rotary swaging

Modeling of extrusion with slip boundary conditions [PDF]
Polymer Engineering & Science, 1988 AbstractSlip at boundaries is possible in viscous flows; for instance, in the extrusion of foodstuffs, water‐containing materials, and some polymers. There are two phenomenological descriptions of slip: The first is based on the presence of a very thin, low viscosity boundary layer and has been derived for capillary flow and extrusion; the second is ...

Advanced Engineering Materials, EarlyView.Building machine‐readable vocabularies for materials science is slow, expert‐driven work. This study benchmarks 13 large language models on two of its first steps: finding candidate terms in engineering articles and deciding where they belong in a class hierarchy.

Microstructure Evolution of a VMnFeCoNi High‐Entropy Alloy After Synthesis, Swaging, and Annealing
Advanced Engineering Materials, EarlyView.The synthesis and processing (rotary swaging and annealing) of the novel VMnFeCoNi alloy is investigated, alongside the estimation of the grain size effect on hardness. Analysis of a wide grain size range of recrystallized microstructures (12–210 µm) reveals a low annealing twin density.

Drag-Reduction Characteristics in Air Flow over the Iced Surface at Re>104 [PDF]
International Journal of Advanced Design and Manufacturing Technology, 2008 This paper studied the mathematical method of flow with regard to two-Phase boundary layer that created over the iced surface. Based on experimental results, skin drag over the iced surface compared with this force that compute with slip condition. Based

Stokes flow with slip and Kuwabara boundary conditions
Proceedings Mathematical Sciences, 2002 The steady Stokes flow of a fluid volume bounded by two parallel surfaces is considered. The boundary conditions are: i) vanishing of the normal component of velocity and slip condition on the inner (solid) surface, ii) continuity of the normal component of velocity and vanishing of vorticity on the outer (cell) surface.

Advanced Engineering Materials, EarlyView.The temperature dependence of fatigue behavior in nickel‐based superalloys is investigated through high‐resolution measurements of plastic localization. While increasing temperature reduces localization and enhances fatigue performance in René 88DT, Inconel 718 exhibits a sharp degradation at intermediate temperature due to intensified slip ...
