Wandering Corrections from PIV Measurements of Tornado-Like Vortices
Wandering of tornado-like vortices consists in random oscillations of the vortex core from its time-averaged position, which complicates efforts to characterize vortex characteristics. A procedure is then necessary to ... -
Quantification of the Axial Induction Exerted by Utility-Scale Wind Turbines by Coupling LiDAR Measurements and RANS Simulations
The axial induction exerted by utility-scale wind turbines for different operative and atmospheric conditions is estimated by coupling ground-based LiDAR measurements and RANS simulations. The LiDAR data are thoroughly ... -
Coupling of Mesoscale Weather Research and Forecasting Model to a High Fidelity Large Eddy Simulation
Numerical simulations of the flow in a wind farm in north Texas have been performed with WRF (Weather Research and Forecasting model) and our in-house LES code. Five nested domains are solved with WRF to model the meso-scale ... -

Effects of Incoming Wind Condition and Wind Turbine Aerodynamics on the Hub Vortex Instability
Dynamics and instabilities occurring in the near-wake of wind turbines have a crucial role for the wake downstream evolution, and for the onset of far-wake instabilities. Furthermore, wake dynamics significantly affect the ... -
Data-Driven RANS for Simulations of Large Wind Farms
