A comparison of lab-scale free rotating wind turbines and actuator disks
Helvig, Sanne de Jong (Master thesis, 2020)Planar particle image velocimetry ble gjennomført oppstrøms og i den nærliggende vaken til en roterende vindturbinmodell i laboratorieskala og aktuatordisker av samme dimensjon i en vindtunell. Den innkommende strømningen ... -
The actuator disk as a wind turbine model: An experimental assessment of the fluid dynamics
Vinnes, Magnus Kyrkjebø (Doctoral theses at NTNU;2023:9, Doctoral thesis, 2023)Climate change is one of the major challenges of our time. With ambitions to keep the average global temperature below 1:5ý C above pre-industrial levels, significant efforts to transform the global energy production from ... -
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 ... -
Characterizing porous disk wakes in different turbulent inflow conditions with higher-order statistics
Vinnes, Magnus Kyrkjebø; Neunaber, Ingrid; Lykke, Hauk-Morten Heimlund; Hearst, Robert Jason (Peer reviewed; Journal article, 2023)The wakes of a uniform and a non-uniform porous disk exposed to two different turbulent flows are investigated experimentally. The disks are representative of static wind turbine models found in literature. Six wake profiles ... -
A comparison of lab-scale free rotating wind turbines and actuator disks
Helvig, Sanne de Jong; Vinnes, Magnus Kyrkjebø; Segalini, Antonio; Worth, Nicholas; Hearst, R. Jason (Peer reviewed; Journal article, 2021)Planar particle image velocimetry was conducted upstream and in the near-wake of a lab-scale free-rotating wind turbine model and compared to several actuator disks with the same dimensions. The Reynolds number of the ... -
The far wake of porous disks and a model wind turbine: Similarities and differences assessed by hot-wire anemometry
Vinnes, Magnus Kyrkjebø; Gambuzza, Stefano; Ganapathisubramani, Bharathram; Hearst, Robert Jason (Peer reviewed; Journal article, 2022)The wakes of two different porous disks have been evaluated experimentally. Such disks are commonly used as physical actuator disk analogs for wind turbines. One disk is made of a uniform wire mesh, while the other has a ... -
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 ... -
PIV of the Flow Over a NREL S826 Airfoil Subjected to Different Ice Accretions
Vinnes, Magnus Kyrkjebø; Li, Leon; Hearst, R. Jason (Chapter, 2019). The results have been compared to previously acquired force measurements. For streamlined ice accretions, increased surface roughness and changes to the combined airfoil-ice geometry lead to reduced aerodynamical performance ... -
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 ...
