Machine-learning identification of the variability of mean velocity and turbulence intensity for wakes generated by onshore wind turbines: Cluster analysis of wind LiDAR measurements

G. Valerio Iungo, Romit Maulik, S. Ashwin Renganathan +1

Wind turbine wakes are the result of the extraction of kinetic energy from the incoming atmospheric wind exerted from a wind turbine rotor. Therefore, the reduced mean velocity and…

Data-Driven Wind Turbine Wake Modeling via Probabilistic Machine Learning

S. Ashwin Renganathan, Romit Maulik, Stefano Letizia +1

Wind farm design primarily depends on the variability of the wind turbine wake flows to the atmospheric wind conditions, and the interaction between wakes. Physics-based models tha…
