Experimental validation of unsteady models for fluid structure interaction: Application to yacht sails and rigs [PDF]

open access: yes, 2012
• We present full scale measurements on a yacht sailing upwind in moderate head swell • We highlight the unsteadiness of the loads : peaks may be twice the mean value • The dynamic behavior differs from the steady state : hysteresis loop • Experimental ...

Air‐Pressure–Actuated Vibroacoustic Metamaterial With Tunable Bandgap: Design, Modeling, and Characterization

open access: yesAdvanced Engineering Materials, EarlyView.
This article presents the design, modeling, and characterization of air‐pressure–actuated programmable vibroacoustic metamaterials (PVAMM). The study focuses on leveraging air pressure to dynamically tune resonance frequencies for effective noise attenuation.

Heating of the low-latitude solar wind by dissipation of turbulent magnetic fluctuations

open access: yes, 2001
We test a theory presented previously to account for the turbulent transport of magnetic fluctuation energy in the solar wind and the related dissipation and heating of the ambient ion population. This theory accounts for the injection of magnetic energy

Dielectric Barrier Discharge Plasma Deoxidation of Natively Oxide Layer of Copper Powders in a Fluidized Bed

open access: yesAdvanced Engineering Materials, EarlyView.
This paper presents a novel approach to reducing oxide layers on metal powders using low‐temperature hydrogen dielectric barrier discharge plasmas at atmospheric pressure. Unlike conventional hydrogen‐plasma reductions, the powders do not contact the plasma directly.

Research on Ship Navigation in Numerical Simulation of Weather and Ocean in a Bay [PDF]

open access: yesTransNav, 2012
For safe navigation, high-resolution information on tidal current, wind and waves is very important. In coastal areas in particular, the weather and ocean situation change dramatically in time and place according to the effects of geography and water ...

Air-sea interactions in the marginal ice zone

open access: yesElementa: Science of the Anthropocene, 2016
The importance of waves in the Arctic Ocean has increased with the significant retreat of the seasonal sea-ice extent. Here, we use wind, wave, turbulence, and ice measurements to evaluate the response of the ocean surface to a given wind stress within ...

Ocean Wave Simulation Based on Wind Field. [PDF]

open access: yesPLoS ONE, 2016
Ocean wave simulation has a wide range of applications in movies, video games and training systems. Wind force is the main energy resource for generating ocean waves, which are the result of the interaction between wind and the ocean surface.

Solid‐State Diffusion and Intermetallic Phase Formation in Roll‐Bonded Mg–Zn Composites With Kirigami‐Patterned Inlay

open access: yesAdvanced Engineering Materials, EarlyView.
Mg–Zn composites with a thickness of 0.21 mm were fabricated using roll bonding of a kirigami‐patterned Mg alloy inlay within a Zn matrix. Thermal activation following this process led to the formation of tailored intermetallic structures, which provided the composite with enhanced flexural strength.

Horizon effects with surface waves on moving water

open access: yes, 2010
Copyright © 2010 IOP PublishingSurface waves on a stationary flow of water are considered, in a linear model that includes the surface tension of the fluid. The resulting gravity-capillary waves experience a rich array of horizon effects when propagating
