    • Aerodynamics of an airfoil with leading-edge icing 

      Vinnes, Magnus Kyrkjebø; Hearst, R. Jason (Peer reviewed; Journal article, 2021)
      Two super duplex stainless steels (SDSS) with different W content, namely UNS S32750 (W-free) and UNS S39274 (2.1 wt.% W), were tested in simulated crevice corrosion environments to determine the influence of W on their ...

    • Airfoil optimization for wind turbine application 

      Hansen, Thomas Henrik Hertzfelder (Peer reviewed; Journal article, 2018)
      An airfoil optimization method for wind turbine applications that controls the loss in performance due to leading edge contamination is developed and tested. The method uses the class-shape-transformation technique to ...

    • An experimental study on the effects of winglets on the tip vortex interaction in the near wake of a model wind turbine 

      Bartl, Jan; Mühle, Franz Volker; Hansen, Thomas; Adaramola, Muyiwa S.; Sætran, Lars Roar (Peer reviewed; Journal article, 2020)
      An experimental study of the near wake up to four rotor diameters behind a model wind turbine rotor with two different wing tip configurations is performed. A straight‐cut wing tip and a downstream‐facing winglet shape are ...

    • The flow in the induction and entrance regions of lab-scale wind farms 

      Vinnes, Magnus Kyrkjebø; Worth, Nicholas Alexander; Segalini, Antonio; Hearst, Robert Jason (Peer reviewed; Journal article, 2023)
      With the increasing demand for wind energy, it is important to be able to understand and predict the available wind resources. To that end, the present wind tunnel study addresses the flow in the induction and entrance ...

    • Performance and wake of a Savonius vertical‐axis wind turbine under different incoming conditions 

      Aliferis, Alexander D; Jessen, Marius Stette; Bracchi, Tania; Hearst, R. Jason (Journal article; Peer reviewed, 2019)
      In this study, the performance, drag, and horizontal midplane wake characteristics of a vertical‐axis Savonius wind turbine are investigated experimentally. The turbine is drag driven and has a helical configuration, with ...

    • Wind tunnel investigation on the effect on the turbine tower on wind turbines wake symmetry 

      Pierella, F; Sætran, Lars Roar (Journal article; Peer reviewed, 2017)
      In wind farms, the wake of the upstream turbines becomes the inflow for the downstream machines. Ideally, the turbine wake is a stable vortex system. In reality, because of factors like background turbulence, mean flow ...

    • Winglet optimization for a model-scale wind turbine 

      Hansen, Thomas Henrik Hertzfelder; Mühle, Franz Volker (Peer reviewed; Journal article, 2018)
      A winglet optimization method is developed and tested for a model-scale wind turbine. The best-performing winglet shape is obtained by constructing a Kriging surrogate model, which is refined using an infill criterion based ...
