    • Blind test comparison on the wake behind a yawed wind turbine 

      Mühle, Franz Volker; Schottler, Jannik; Bartl, Jan Michael Simon; Futrzynski, Romain; Evans, Steve; Bernini, Luca; Schito, Paolo; Draper, Martín; Guggeri, Andrés; Kleusberg, Elektra; Henningson, Dan S.; Hölling, Michael; Peinke, Joachim; Adaramola, Muyiwa S.; Sætran, Lars Roar (Journal article; Peer reviewed, 2018)
      This article summarizes the results of the “Blind test 5” workshop, which was held in Visby, Sweden, in May 2017. This study compares the numerical predictions of the wake flow behind a model wind turbine operated in yaw ...

    • Grand challenges in the science of wind energy 

      Veers, Paul; Dykes, Katherine; Lantz, Eric; Barth, Stephan; Bottasso, Carlo L.; Carlson, Ola; Clifton, Andrew; Green, Johney; Green, Peter; Holttinen, Hannele; Laird, Daniel; Lehtomäki, Ville; Lundquist, Julie K.; Manwell, James; Marquis, Melinda; Meneveau, Charles; Moriarty, Patrick; Munduate, Xavier; Muskulus, Michael; Naughton, Jonathan; Pao, Lucy; Paquette, Joshua; Peinke, Joachim; Robertson, Amy; Rodrigo, Javier Sanz; Sempreviva, Anna Maria; Smith, J Charles; Tuohy, Aidan; Wiser, Ryan (Journal article; Peer reviewed, 2019)
      Modern wind turbines already represent a tightly optimized confluence of materials science and aerodynamic engineering. Veers et al. review the challenges and opportunities for further expanding this technology, with an ...

      Dykes, Katherine; Veers, Paul; Lantz, Eric; Holttinen, Hannele; Carlson, Ola; Tuohy, Aidan; Sempreviva, Anna Maria; Clifton, Andrew; Rodrigo, Javier Sanz; Berry, Derek; Laird, Daniel; Carron, Scott; Moriarty, Patrick; Marquis, Melinda; Meneveau, Charles; Peinke, Joachim; Johnson, Nick; Pao, Lucy; Fleming, Paul; Bottasso, Carlo L.; Lehtomäki, Ville; Robertson, Amy; Muskulus, Michael; Manwell, Jim; Tande, John Olav Giæver; Sethuraman, Latha; Roberts, Owen; Fields, Jason (Research report, 2019)
      The wind industry has realized substantial growth reaching over 500 gigawatts (0.5 terawatts) of installed capacity in 2017 (Global Wind Energy Council 2018) and producing about 5% of global electricity demand in 2016 ...

    • Wind tunnel experiments on wind turbine wakes in yaw: effects of inflow turbulence and shear 

      Bartl, Jan Michael Simon; Mühle, Franz Volker; Schottler, Jannik; Sætran, Lars Roar; Peinke, Joachim; Adaramola, Muyiwa S.; Holling, Micheal (Journal article; Peer reviewed, 2018)
      The wake characteristics behind a yawed model wind turbine exposed to different customized inflow conditions are investigated. Laser Doppler anemometry is used to measure the wake flow in two planes at x∕D = 3 and x∕D = 6, ...

    • Wind tunnel experiments on wind turbine wakes in yaw: redefining the wake width 

      Schottler, Jannik; Bartl, Jan Michael Simon; Mühle, Franz Volker; Sætran, Lars Roar; Peinke, Joachim; Hölling, Michael (Journal article; Peer reviewed, 2018)
      This paper presents an investigation of wakes behind model wind turbines, including cases of yaw misalignment. Two different turbines were used and their wakes are compared, isolating effects of boundary conditions and ...
