1. 1. An assessment of circular economy measures in the construction value chain for offshore wind turbines

   University essay from Lunds universitet/Byggproduktion

   Author : Therése Svensson; [2023]
   Keywords : Circular economy; Construction value chain; Wind energy; Offshore wind turbine; Offshore wind farm; Design; Manufacturing; Construction; Operation and maintenance; End of life; Technology and Engineering;

   Abstract : The construction sector is responsible for high energy consumption and large emissions of carbon dioxide, which is strongly linked to building materials. Within the European Union, the construction sector generates more than a third of all waste and circular economy is considered as a suitable approach to tackle these challenges. READ MORE

   Abstract : Due to the increase of rotor size in horizontal axis wind turbine (HAWT) during the past 25 years in order to achieve higher power output, all wind turbine components and blades in particular, have to withstand higher structural loads. This upscalingproblem could be solved by applying technologies capable of reducing aerodynamic loads the rotor has to withstand, either with passive or active control solutions. READ MORE

4. 3. Experimental Investigation of Fluid-added Parameters on a Kaplan Runner

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Author : Malin Strandberg; [2021]
   Keywords : Added mass; added inertia; fluid dynamics; hydropower; Kaplan turbine; fluid-solid interaction;

   Abstract : In order to reach climate and environmental goals, Sweden is increasing the implementation of intermittent renewable energy sources such as wind and solar power to the electricity grid. The increase of intermittent energy sources is rising power regulation requirement towards hydropower, which increasingly exposes the hydraulic turbines to high loads and fluctuating hydraulic forces.

5. 4. Performance analysis of a small-scalewind turbine at variable pitch and withpitch unbalance

   University essay from KTH/Strömningsmekanik och Teknisk Akustik

   Author : Francesco Mazzeo; [2021]
   Keywords : Wind energy; wind turbine; pitch angle; pitch unbalance; Blade Element Momentum BEM theory; Computational Fluid Dynamics CFD ; wind tunnel experiments; oscillations;

   Abstract : When it comes to design a wind turbine rotor, several parameters have to be taken into account. The present work focuses on the inclination of the blades with respect to the rotor plane, namely the pich angle. READ MORE

6. 5. Two-dimensional Study of Blade Profiles for a Savonius Wind Turbine

   University essay from Uppsala universitet/Elektricitetslära

   Author : Johanna Sundberg; Martina Lundberg; Julia Solhed; Aikaterini Manousidou; [2020]
   Keywords : Savonius rotor; vertical axis wind turbines; Ansys Fluent; k-omega SST; overlap ratio; blade arc angle;

   Abstract : A Savonius wind turbine is a self-starting vertical axis rotor. It can be designed to be compact in size and also produces less noise which makes it suitable to integrate into urban spaces such as rooftops and sign-poles. READ MORE
