Wind Energy Installations: New insight!
American Institute of Physics (AIP)
Researchers have developed a new way to study Wind Energy Installations wake effects that includes the airflow both within and around a wind farm and challenges the conventional belief that turbines arrayed in checker board patterns produce the highest power output. Their study provides insight into factors that determine the most favorable positioning.
s wind farms grow in importance across the globe as sources of clean, renewable energy, one key consideration in their construction is their physical design — spacing and orienting individual turbines to maximize their efficiency and minimize any “wake effects,” where the swooping blades of one reduces the energy in the wind available for the ing turbine.
Optimally spacing turbines allows them to capture more wind, produce more power and increase revenue for the farm. Knowing this, designers in the industry typically apply simple computer models to help determine the best arrangements of the turbines. This works well for small wind farms but becomes less precise for larger wind-farms where the wakes interact with one another and the overall effect is harder to predict.
Now a team of researchers at Johns Hopkins University (JHU) has developed a new way to study wake effects that takes into account the airflow both within and around a wind farm and challenges the conventional belief that turbines arrayed in checker board patterns produce the highest power output. Their study provides insight into factors that determine the most favorable positioning — work described in a new paper in the Journal of Renewable and Sustainable Energy, which is produced by AIP Publishing.

The intersection of the oil and gas and geothermal industries is one that is rich in unexpected ways, be it in drilling technologies or the new frontier of co-production of both fossil fuels and geothermal power from the same well.
Environmental Defense Fund (EDF) this week unveiled a vision to collaborate with communities, technical experts, businesses and investors to build low-carbon microgrids in Puerto Rico, and bring reliable, clean and affordable electricity to rural areas of the island. As described at the “BlackStart 2019: Future of Energy Summit” in San Juan, the new initiative will […]

The U.S Jones Act affects the construction of U.S. offshore wind farms by limiting certain activities in U.S. waters to U.S.-registered vessels owned and operated by qualified U.S. citizens. Much of the expertise in the construction of offshore wind farms is European based. The logical mechanism for marrying European expertise with U.S. firms qualified to […]

This fully operational package lets engineers, technicians, and developers initialize, configure and program the control, visualization and communication aspects of their groov EPIC systems. The Learning Center is a suitable companion for Opto 22’s… […]
The move to faster speeds, larger volumes and greater outputs in automated machinery is prompting more use of vibration and shock mitigation technologies. This has intensified innovations to shock absorbers, vibration dampers, air bearings and other devices, which run the gamut from faster response-designs to smart technologies. According to Brian Fink, Product Manager, Aerotech Inc.,… […]
The DN-FE-16T crimping tool has a rotatable die and a trapezoidal crimp profile. The crimper is self-adjusting for use with insulated and non-insulated wire ferrules in sizes from 26 to 8 AWG. The crimp head is rotatable to accommodate crimping from the side or from the front. This new crimper is identical to AutomationDirect’s two… […]
