Tidal Rectification: Friction or Not Friction?

Journal of Physical Oceanography, 1998
Abstract A survey of the theoretical aspects of tidal rectification over a continental slope in the inviscid fluid approximation is proposed. In particular, the geostrophic degeneracy problem, evoked by A. W. Visser to justify the need for friction in the momentum equations, is examined.

Enhancement of the Through‐Thickness Electrical Conductivity of Carbon‐Fiber‐Reinforced Plastics Using Large Graphite Particles

Advanced Engineering Materials, EarlyView.
To enhance through‐thickness conductivity without sacrificing impregnation, large spherical graphite particles are intentionally employed in a low‐viscosity resin. Unlike finer conductive fillers, these particles remain outside the fiber bundles and accumulate in resin‐rich interlaminar regions during molding.

Experimental Investigation of Frictional Resistance in Sliding Contact between Undulating Surfaces and Third-Body Particles

Machines
The third-body particle-involved sliding contact between two rough rubbers with wavy surfaces is experimentally studied. The experiment is designed to isolate the direct contact between the first bodies so that friction resistance is induced completely ...

Stretching the Printability Metric in Direct‐Ink Writing with Highly Extensible Yield‐Stress Fluids

Advanced Functional Materials, EarlyView.
This study introduces “drawability” as a new metric for assessing printability in direct‐ink writing, focusing on gap‐spanning performance and speed robustness. By designing yield‐stress fluids with high extensibility, we demonstrate that extensional strain‐to‐break significantly enhances printability.
