Influence of power take-off on flow field around oscillating water column wave energy converters: An experimental study based on particle image velocimetry

Applied Ocean Research
In oscillating water column (OWC) wave energy converters, the power take-off (PTO) system critically influences energy conversion. Although PTO configurations have been extensively optimized for energy conversion efficiency, their effects on water-column

Global Alfven Wave Heating of the Magnetosphere of Young Stars [PDF]

, 2002
Excitation of a Global Alfven wave (GAW) is proposed as a viable mechanism to explain plasma heating in the magnetosphere of young stars. The wave and basic plasma parameters are compatible with the requirement that the dissipation length of GAWs be ...

Wells Turbine for Wave Energy Conversion

International Journal of Scientific Research and Management (IJSRM), 2018
Wells turbine has innate drawbacks in examination with customary turbines: relative low productivity at high stream coefficient and poor beginning attributes. To take care of these issues, the creators propose Wells turbine with promoter turbine for wave vitality transformation, keeping in mind the end goal to enhance the execution in this examination.

Resistance Rapid Heating of Aluminum Coatings in an Extreme High Vacuum–Adequate Atmosphere for Hot Stamping

Advanced Engineering Materials, EarlyView.
The subject of this work is the development of a corrosion‐protective coating on steel sheets for form hardening. Rapid heating in an extreme high vacuum (XHV)‐adequate atmosphere is a useful method to prevent oxidation during alloying of 22MnB5 and aluminum to obtain a metallurgical bonding.
