A simulation study demonstrating the importance of large-scale trailing vortices in wake steering [PDF]

open access: yesWind Energy Science, 2018
In this paper, we investigate the role of flow structures generated in wind farm control through yaw misalignment. A pair of counter-rotating vortices is shown to be important in deforming the shape of the wake and in explaining the asymmetry of wake ...

Efficiency and spectrum of internal gamma-ray burst shocks [PDF]

open access: yes, 2001
We present an analysis of the Internal Shock Model of GRBs, where gamma-rays are produced by internal shocks within a relativistic wind. We show that observed GRB characteristics impose stringent constraints on wind and source parameters.

Quarter-Century Offshore Winds from SSM/I and WRF in the North Sea and South China Sea

open access: yesRemote Sensing, 2016
We study the wind climate and its long-term variability in the North Sea and South China Sea, areas relevant for offshore wind energy development, using satellite-based wind data, because very few reliable long-term in-situ sea surface wind observations ...

Streaming dynamic mode decomposition for short‐term forecasting in wind farms

open access: yesWind Energy, 2022
Forecasting in wind energy is a crucial task to perform adequate wind farm flow control or to participate in the energy market. While many power forecasting methods exist, it is notoriously difficult to capture both short‐ and long‐term variations in the
