Journal of Physics: Conference Series, 2015 A team of researchers from the National Renewable Energy Laboratory and Statoil used large-eddy simulations to numerically investigate the merging wakes from upstream offshore wind turbines. Merging wakes are typical phenomena in wind farm flows in which neighboring turbine wakes consolidate to form complex flow patterns that are as yet not well ...

Measurement procedures for characterization of wind turbine wakes with scanning Doppler wind LiDARs [PDF]
Advances in Science and Research, 2013 The wake flow produced from an Enercon E-70 wind turbine is investigated through three scanning Doppler wind LiDARs. One LiDAR is deployed upwind to characterize the incoming wind, while the other two LiDARs are located downstream to carry out wake ...

A Comparison of Edge Detectors in the Framework of Wake Pattern Modeling for Wind Turbines
International Journal of Prognostics and Health Management, 2015 To monitor wind turbine health, wind farm operators can take advantage of the historical SCADA (supervisory control and data acquisition) data to generate the wake pattern beforehand for each wind turbine, and then decide in real time whether observed ...

Asset Redeployability and Biodiversity Risk
Business Strategy and the Environment, EarlyView.ABSTRACT We examine how asset redeployability influences a firm's exposure to biodiversity risk. Our empirical analysis provides robust evidence that firms possessing greater levels of redeployable assets exhibit significantly lower biodiversity risk.
