CFD simulations of local wind fields : a parametric study
Birkeland, Vincent Kortebein (Master thesis, 2021)Establishing the local wind fields using a simulation software is an important part of the wind resource assessment. In this study the WindSim software, utilizing the Computational Fluid Dynamics (CFD) method, is used to ... -
Estimation of production losses due to icing on wind turbines at Kvitfjell wind farm
Kjersem, Håkon Albrigtsen (Master thesis, 2019)Wind farms in cold climates are known for their challenge’s with lowered performance due to icing on wind turbine blades, but there is little knowledge around the correlation between wind, ice and energy production which ... -
Validation of a wind farm wake model based on the actuator disc concept in complex terrain
Ladstein, Ansgar Johan (Master thesis, 2018)A wind turbine operating downwind of another will stand in the wake of the upstream turbine, resulting in decreased power generation and increased load fatigue. In order to keep wake losses at a minimum, wind farm designers ...
