    • Data-Driven RANS for Simulations of Large Wind Farms 

      Iungo, Giacomo V.; Viola, F.; Ciri, Umberto; Rotea, Mario A.; Leonardi, Stefano
      In the wind energy industry there is a growing need for real-time predictions of wind turbine wake flows in order to optimize power plant control and inhibit detrimental wake interactions. To this aim, a data-driven RANS ...
    • Data-Driven Reduced Order Model for Prediction of Wind Turbine Wakes 

      Iungo, Giacomo V.; Santoni-Ortiz, Christian; Abkar, M.; Porté-Agel, F.; Rotea, Mario A.; Leonardi, Stefano
      In this paper a new paradigm for prediction of wind turbine wakes is proposed, which is based on a reduced order model (ROM) embedded in a Kalman filter. The ROM is evaluated by means of dynamic mode decomposition performed ...
    • Effects of Incoming Wind Condition and Wind Turbine Aerodynamics on the Hub Vortex Instability 

      Ashton, Ryan; Viola, F.; Gallaire, F.; Iungo, Giacomo V.
      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 ...
    • Numerical Study on Uniform-Shear Flow over a Circular Disk at Low Reynolds Numbers 

      Yang, J.; Liu, M.; Wang, C.; Zhu, Xiaowei; Zhang, A.
      Uniform shear flows over a circular disk of aspect ratio 10 (thickness/diameter) at low Reynolds numbers are numerically investigated with the main focus on the effect of inlet shear on the wake evolutions. The Reynolds ...
