Wu, Chun-Yen (author)The increasing focus on sustainable living and the need to reduce dependency on fossil fuels has led to a growing interest in renewable energy sources. Among these, the wind energy sector has not only experienced significant growth in terms of numbers but also in size. Larger turbines lead to more severe leading-edge erosion and further increase...master thesis 2023

te Lintelo, Thomas (author)More and more wind turbines are erecting in the landscape, stemming from the need for sustainable energy. However, less attention is paid to the secondary effects of these wind turbines, more specifically, the wind turbine blades. Wind turbine blades are made of composite material, a material that provides many advantageous properties for the...master thesis 2023

Brans, Karel (author)The goal of this thesis project was to explore how material originating from thermoplastic composite wind turbine blades (TPC WTB) can be reshaped. The insights gained during exploratory activities were used to design a re-use application. The demonstrator model should inspire people to develop other applications and build upon the foundations...master thesis 2023

John Vaseekaran, Saran (author)Leading Edge Erosion is a major concern for the wind energy industry as it affects the aerodynamic efficiency of wind turbine blades and, therefore, the power generated. Hail impact on the leading edge could significantly damage the protective layer and the composite substrate. The focus of this research study is to investigate the effect of...master thesis 2023

Nguyen, Binh Minh (author)An increasing massive volume of wind turbine blades are coming to end-of-life in the Netherlands. These components contain mostly fibre-reinforced plastics, which has been banned from landfill and incineration. Since then, companies and institutions have spent their efforts to expand the lifetime of this material by developing a circular wind...master thesis 2023

Savana, Reshab (author)The growing demand for renewable energy has led to significant developments in wind turbine technology. The ever increasing size of turbine blades and their exposure to a variety of environmental factors can affect their annual energy production and service life. Erosion caused by rainfall and hailstones is identified as two of the most...master thesis 2022

VOULTSOS, IOANNIS (author)The energy transition towards carbon neutrality requires a rapid electrification of all energy sectors by 2050. In the EU-27, the REPowerEU strategy, initiated in March 2022, is pursuing this target even more ambitiously. However, in order to achieve the aforementioned goals, the increasing demand for green hydrogen will...master thesis 2022

Przespolewski, Adriaan (author)This report covers the development of the Blade Barrier: A sound barrier constructed using decommissioned wind turbine blades.<br/>The ever-growing wind industry faces a composite waste problem. Wind turbine blades only last a few decades, and are difficult and therefore not economically desirable to recycle.<br/>One proposed solution to this...master thesis 2022

Pronk, Simon (author)Wind turbines are decommissioned when they reach their endoflife. The reason for reaching endoflife varies per wind turbine, but they all have in common that the wind turbine blades can not be recycled and thus end up as waste. Since a growing amount of wind turbines will reach their endoflife the coming decade, the waste problem will increase....master thesis 2022

Scheepens, Wiebke (author)Wind turbine blades are composed of complex composite material structures that are difficult to recycle at the end of their operational lifetime. As such, they are oftentimes landfilled or incinerated. Following the Circular Economy principles, there are a multitude of strategies that may be applied to these structures; these range from more to...master thesis 2021

Foulds, Deacon (author)Wind energy is a growing industry, and in an effort to reduce costs and increase turbine efficiency, rotor blades are becoming increasingly large in size. To facilitate this effort, the SmartBlades2 research project has designed, built, and tested a set of prototype research blades. As part of the SmartBlades2 project, high sensor density modal...master thesis 2021

Sanchez Bravo, Alex (author)Wind turbines play an increasingly imporant role in the energy production of our time. In order to optimize the performance of wind turbine blades, this thesis work aims at assessing the possibility of using panel methods for gradient based optimization of the aerodynamics of wind turbine blades. Specifically, the method employed has used...master thesis 2021

Mathew, Joan (author)With a growing demand for longer blades in the wind turbine industry for higher rated power per turbine, a structurally sound blade-root connection is of commercial importance. Bushing connections have been a commercially favoured design in the past few years, replacing the commonly used T-bolt connection as the joining method of choice. The new...master thesis 2021

Ballapur Jayasimha, Athreya (author)Horizontal Axis Wind Turbines (HAWTs) are a very popular source of renewable energy, but these machines are often subject to off-design conditions owing to the unsteady nature of wind. Unsteady aerodynamic conditions have been associated with cyclic loading of turbine blades, which can have hugely detrimental effects on their operational life....master thesis 2020

Roeleven, Niek (author)This thesis concerns the optimal design of wind turbine blades for bend twist coupling effects. Bend-twist coupling effects can prove to be an effective way of reducing fatigue damage and root bending moments for a wind turbine blade. However, how can bend-twist coupling be incorporated into a wind turbine blade considering the many structural...master thesis 2018

de Ronde, Remko (author)Future wind turbines require larger rotor blade radius, leading to an increase of rotor swept area. The larger rotor swept area results in more energy production of the wind turbine. Further increase is however limited as a result of the structural weight, which induces a large bending moment and could result in buckling of the rotor blade. An...master thesis 2018
