Janoff, Philipp (author)Leading edge roughness is an important challenge for the wind energy industry as blades are permanently exposed to the damaging impacts of the environment. The contamination due to impact of insects, ice accretion and dust; as well as the erosion of the blade due to rain, debris and abrasive airborne particles increase roughness upon the surface...master thesis 2023

van Kan, Ferran (author)A study is conducted on the effects of tip-mounted rotors on a conventional Darrieus H-VAWT; this study is complementary to the X-rotor concept proposal. This proposal features a novel offshore wind turbine concept that utilises blade-mounted tip rotors to extract energy from the flow. Following a literature study phase, an experimental campaign...master thesis 2023

Knepper, Jorian (author)The aerodynamic behaviour of a pitched baseball depends on the combination of the translational velocity, the rotational velocity in combination with the rotation axis and the seam positions. For small spin parameters the effect of seam positions dominates the Magnus effect. This study focusses on a visual understanding of the seam position by...master thesis 2022

Vergés i Plaza, Guillem (author)Trailing-edge noise can be the dominant noise source of diverse industrial applications, including wind turbines. Noise regulations may limit the power production and installation of new wind farms. There is a need to reduce it. In order to achieve so, we first need to predict it, and to do so we need experimental data to support and validate...master thesis 2022

Rasch, Tycho (author)Wind loads acting on STS cranes are an important design parameter to be taken into account when designing STS cranes. Current calculation standards such as the EN13001-2 overestimate wind forces. The goal of this research is to propose an improvement on current calculation standards. Wind tunnel tests were performed to assess the results of...master thesis 2022

Mathijssen, Lucas (author)Supersonic panel flutter is a self-excited vibration, where energy is transferred into thin flexible panels, such as skin panels in supersonic vehicles, from the (supersonic) flow around them, which can lead to their rapid fatigue failure. Relevant examples of this include the failure of skin panels in the X-15 vehicle, or violent oscillations...master thesis 2022

Schildkamp, Roderick (author)With the increased focus on sustainability, aircraft are designed to reduce their emissions. One way to accomplish this is by increasing the wing aspect ratio, thereby increasing the aerodynamic efficiency, however this is not without consequences. Increased aspect ratio wings have a higher structural mass, are more susceptible to gust and...master thesis 2022

van Hulst, Jeffrey (author)One of the basic principles of the design of structures is that they must be sufficiently safe and meet the required reliability requirements. In Eurocode NEN-EN 1990 specific minimum reliability index values are defined, which depend on a certain reference period and reliability class. To ensure that the structures meet the reliability...master thesis 2021
