Dsouza, Brian (author)Wind turbine power output has grown massively over the past few decades, and this has been achieved in part by increasing the size of rotors. But the size of rotors is now limited by structural constraints as well as space constraints in wind farms. It is therefore important to use other innovative methods to increase wind turbine capacity...master thesis 2021

Keijer, Wessel (author)The vertical axis wind turbine (VAWT) concept in its current, fixed-pitch iteration is hindered by lower aerodynamic efficiency compared to existing horizontal axis wind turbines. Implementing a form of circulation control on the VAWT by actively pitching the blades throughout the turbine’s rotation could potentially enhance power capture...master thesis 2020

Lu, Willie (author)This research presents the modelling of struts of a vertical axis wind turbine and its effects on the wake and performance. The 3D non-linear lifting line solver CACTUS is extended to include the struts in the rotor as lifting bodies. A case study is performed for different strut configurations in the rotor, with the focus set on the inclination...master thesis 2020

de Korte, Bart (author)Within this thesis influence of thrust vectoring for VAWTs, controlling the magnitude and direction of the thrust vector with respect to the freestream, is investigated through active pitch actuation. The H-type Darrieus VAWT is modelled in 2D through the actuator cylinder model with the Mod-Lin correction included. The evaluations are performed...master thesis 2019

Li, Ang (author)The aim of this thesis is to evaluate the influence between the two counter-rotating VAWT rotors with the Double Actuator Cylinder (DAC) model which will be validated against the panel code. The DAC model is developed from the original Actuator Cylinder (AC) model which includes the Modified-Linear (Mod-Lin) correction. The original AC model for...master thesis 2017
