Flow field and performance of a vertical-axis wind turbine on model buildings
Jooss, Yannick; Bolis, Roberto; Bracchi, Tania; Hearst, R. Jason (Journal article, 2022)The placement of a scaled-down Savonius (drag) vertical-axis wind turbine on model buildings is analysed experimentally by the use of turbine performance and flow field measurements in a wind tunnel. The set-up consists ... -
A fluid mechanic view on urban wind energy
Jooss, Yannick (Doctoral theses at NTNU;2022:283, Doctoral thesis, 2022)The world energy demand is rising with an increasing need for renewable and sustainable energy sources. Wind energy plays a key role in this transition. Urban areas are largely unexploited for wind energy extraction. Urban ... -
Influence of incoming turbulence and shear on the flow field and performance of a lab-scale roof-mounted vertical axis wind turbine
Jooss, Yannick; Hearst, Robert Jason; Bracchi, Tania Kalogiannidis (Peer reviewed; Journal article, 2023)Flow conditions in an urban environment are complex, featuring varying levels of turbulence intensity and shear. The influence of these flow characteristics on the performance of a roof-mounted vertical axis wind turbine ... -
Influence of position and wind direction on the performance of a roof mounted vertical axis wind turbine
Jooss, Yannick; Rønning, Eivind Berg; Hearst, Robert Jason; Bracchi, Tania (Peer reviewed; Journal article, 2022)The ideal position for a roof mounted wind turbine is investigated experimentally in a wind tunnel. The set-up consists of two cube-shaped buildings. A Savonius (drag driven) vertical axis wind turbine is placed on one of ... -
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 ...
