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.
A “washdown environment” is one that utilizes either by hand or by automatic means, cleaning with water, chemicals, or a mixture of these. This washdown process can be as simple as a cloth and bucket, use of a hose to spray clean, or it can be under sophisticated high pressure and controlled systems. The design… […]
New Allen-Bradley FLEX 5000 safety I/O modules can meet the needs of producers in process and heavy industries that require fixed field-wiring terminations or both vertical and horizontal I/O mounting in their distributed safety applications. The three new FLEX 5000 safety I/O modules provide distributed safety I/O for the Allen-Bradley Compact GuardLogix 5380 and GuardLogix… […]
