Affecting the Properties of Copper–Graphene Electroconductive Composite by Severe Plastic Deformation

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

Inverse Identification of Energy‐Dependent Laser Absorptivity in NiTi Laser Powder‐Bed Fusion via Calibrated Melt Pool Simulation

Advanced Engineering Materials, EarlyView.
A combined experimental–computational framework identifies energy‐dependent laser absorptivity for NiTi in laser powder‐bed fusion, applicable to conduction and transition modes. Single‐track experiments and thermofluid smoothed particle hydrodynamics simulations are coupled through inverse analysis of melt pool geometry.

Influence of Rough Flow over Sea Surface on Dry Atmospheric Deposition Velocities

Terrestrial, Atmospheric and Oceanic Sciences, 2013
A Meteorological model and a dry deposition module were used to estimate the effects of sea surface rough flow (SSRF) over the sea surface on dry deposition velocities. The dry deposition turbulence resistance, Ra, and sub-layer resistance, Rb, decreased

On the Dependence of Sea Surface Roughness on Wind Waves

Journal of Physical Oceanography, 1998
Abstract The influence of wind waves on the momentum transfer (wind stress) between the atmosphere and sea surface was studied using new measured data from the RASEX experiment and other datasets compiled by Donelan et al. Results of the data analysis indicate that errors in wind friction velocity u∗ of about ±10% make it difficult to conclude on the ...

Modelling impact of bottom roughness on sea surface temperature in the Sea of Iroise [PDF]

Continental Shelf Research, 2013
A hydrological model based on the coupling of the three-dimensional hydrodynamic module COHERENS (COupled Hydrodynamical-Ecological model for RegioNal and Shelf seas) with the wave propagation module SWAN (Simulating WAves Nearshore) is used to study the effects of bottom roughness on sea surface temperature (SST) in the nearshore areas of the Sea of ...

Analysis of the land surface heterogeneity and its impact on atmospheric variables and the aerodynamic and thermodynamic roughness lengths [PDF]

, 2008
The land surface heterogeneity has a very significant impact on atmospheric variables (air temperature T-a, wind speed u, and humidity q), the aerodynamic roughness length z(0m), thermodynamic roughness length z(0h), and the excess resistance to heat ...
