• Aerodynamics of an airfoil subjected to icing 

      Kyrkjebø, Magnus (Master thesis, 2018)
      Wind turbines located in cold climate face several issues due to ice accretion. These include power losses, mechanical failures and changes in the aerodynamic behaviour. Particle image velocimetry measurements have been ...
    • Performance and wake measurements of a Savonius wind turbine 

      Jessen, Marius Stette; Aliferis, Alexander Dahl (Master thesis, 2018)
      In this study, the performance, drag and wake characteristics of a vertical axis Savonius wind turbine are investigated experimentally. The turbine is drag driven and has a helical configuration, making the top rotated 180 ...
    • Signifikant Reduksjon i Luftmotstanden på en Sylinder ved bruk av Striper og Tekstiler 

      Skeide, Arne Kilvik (Master thesis, 2019)
      Effekten av striper og små-skala overflateruhet på luftmotstanden og virvelavløsningen til en sirkulær sylinder, har blitt undersøkt. En sylinder ble dekket av et 'tekstil' bestående av halvsirkulære striper liggende ...
    • Spatial development of a turbulent boundary layer subjected to freestream turbulence 

      Jooss, Yannick; Li, Leon; Bracchi, Tania; Hearst, Robert Jason (Peer reviewed; Journal article, 2021)
      The spatial development of a turbulent boundary layer (TBL) subjected to freestream turbulence (FST) is investigated experimentally in a water channel for friction Reynolds numbers up to Reτ=5060. Four different FST ...
    • The effect of turbulence and blockage orientation on the near-field of porous disks 

      Lykke, Hauk-Morten Heimlund (Master thesis, 2019)
      Vindtunnel-eksperimenter har blitt gjennomført med en solid disk og to ulike porøse disker med identisk soliditet plassert i strømninger med to forskjellige turbulens-intensiteter med et Reynoldstall på Re =110 000. En av ...
    • Uniform-momentum zones in a turbulent boundary layer subjected to freestream turbulence 

      Hearst, Robert Jason; de Silva, Charitha; Dogan, Eda; Ganapathisubramani, Bharathram (Peer reviewed; Journal article, 2021)
      The instantaneous structure of a turbulent boundary layer that has developed beneath freestream turbulence (FST) was investigated with planar particle image velocimetry. Measurements were performed in the streamwise–wall-normal ...
