Vesper, J.E. (author)Physical Vapor Deposition (PVD) is the resublimation of a substance on a cold surface coating it with a thin solid layer. PVD coatings are utilized in industry to modify surface properties and appearance. Since the industrial process requires vacuum conditions, it has been mainly conducted in a batch process. Recently, PVD is considered a...doctoral thesis 2022

VanDercreek, Colin (author)<br/>Aerodynamic noise produced by aircraft, wind turbines, and other objects subjected to airflow contribute to environmental noise pollution, which adversely affects human and animal health. Consequently, governments impose restrictions on aircraft and wind turbine noise levels. These restrictions can have an economic impact by limiting...doctoral thesis 2022

Star, Quinten (author)Perforated monopiles show promise in providing a better alternative to the commonly used jacket-like substructures used in intermediate water depths in the range of 30 to 120 m. By introducing perforations near the vicinity of the splash zone the wave loads on the monopile can be mitigated and the fatigue damage reduced, which is the main...master thesis 2022

Eijkhout, Thijs (author)Wind turbines have proven to be an essential part for the green energy mix. However, the focus was mainly on the horizontal axis wind turbines whereas the vertical axis wind turbine did not receive that amount of attention. In this work a straight-bladed vertical axis wind turbine (SB-VAWT) is explored which can temporary adjusts its rotor...master thesis 2022

Kokkedee, Jop (author)With an ever increasing demand for sustainable energy, limitations of current sustainable technologies are studied widely. In wind farms, the so-called wake effect provides the biggest limitation on wind farm total power output. Using wind from the unaffected boundary layer to re-energize the wind flow in the wake provides a method of limiting...master thesis 2022

Dos Santos Pereira Malveiro, Carlos (author)The most effective way to decrease the cost of energy of wind turbines is to increase the rotor diameter. Therefore, this calls for the need of aerodynamic research on large wind turbines. This thesis project will tackle the topics addressed by the IEA Wind Task 47 which is focused on the aerodynamic analysis and comparison of the newly proposed...master thesis 2022

van Koelen, Luc (author)Weirs are constructed inside rivers to manage the water level. On the one hand they need to be designed sufficiently strong to prevent failure or destruction, while on the other hand they need to be economically feasible. If a structure is designed too strong, unnecessary costs are made and the structure becomes too expensive.<br/><br/>One of...master thesis 2022
