Power performance of a model floating wind turbine subjected to cyclic pitch motion: A wind tunnel study
Fernando Porté Agel, Guiyue Duan, Daniele Gattari
Wind tunnel experiments were performed with a miniature floating wind turbine model to study the effects of cyclic pitch motion on its power performance. The cyclic pitch motion was prescribed by two key parameters: pitch frequency and amplitude. The power ...
IOPscience2024The effect of nacelle-to-rotor size on the wake of a miniature wind turbine
Fernando Porté Agel, Arslan Salim Dar, Rim Majzoub
Wind tunnel experiments are performed to investigate the effect of nacelle-to-rotor size on the wake of a wind turbine under different Reynolds numbers. Four different turbine configurations are tested, which vary in the rotor diameter and nacelle length a ...

2024Enhancing Wind Farm Performance through Axial Induction and Tilt Control: Insights from Wind Tunnel Experiments
Fernando Porté Agel, Guillem Armengol Barcos
Static axial induction control and tilt control are two strategies that have the potential to increase power production in wind farms, mitigating wake effects and increasing the available power for downstream turbines. In this study, wind tunnel experiment ...
Basel2024Optimal blade pitch control for enhanced vertical-axis wind turbine performance
Karen Ann J Mulleners, Sébastien Le Fouest
Vertical-axis wind turbines are great candidates to enable wind power extraction in urban and off-shore applications. Currently, concerns around turbine efficiency and structural integrity limit their industrial deployment. Flow control can mitigate these ...
2024CFD-based analysis of pumped storage power plants implementing hydraulic short circuit operations
Elena Vagnoni, Alessandro Morabito
Hydraulic short circuit (HSC), corresponding to the simultaneous operation of the pumps and turbines, enhances the power flexibility of a pumped storage power plant (PSPP). However, comprehensive analyses are imperative to guarantee a secure and reliable o ...
Elsevier Sci Ltd2024Wind turbine wake superposition under pressure gradient
Fernando Porté Agel, Arslan Salim Dar
We investigate the effect of pressure gradient on the cumulative wake of multiple turbines in wind tunnel experiments spanning across a range of adverse pressure gradient (APG), zero pressure gradient (ZPG), and favorable pressure gradient (FPG). Compared ...
2024Power performance of a model floating wind turbine subjected to cyclic pitch motion: A wind tunnel study
Fernando Porté Agel, Guiyue Duan, Daniele Gattari
Offshore floating wind turbines (OFWTs) are becoming increasingly popular due to their ability to exploit deep-sea wind resources. However, since wind turbines are installed on floaters instead of solid foundations, the dynamic response of an OFWT due to ...
2024Parametric Reduced Order Model of a Gas Bearings Supported Rotor
Fabio Nobile, Jürg Alexander Schiffmann, Dimitri Maurice Goutaudier
Gas bearings use pressurized gas as a lubricant to support and guide rotating machinery. These bearings have a number of advantages over traditional lubricated bearings, including higher efficiency in a variety of applications and reduced maintenance requi ...
2024Readiness evaluation of SOFC-MGT hybrid systems with carbon capture for distributed combined heat and power
Jan Van Herle, Jürg Alexander Schiffmann, Victoria Xu Hong He, Michele Gaffuri
The aggravation of climate change calls for the timely development and implementation of highly efficient, renewable, zero- or negative-emission energy solutions with high technological readiness and feasibility levels. Solid oxide fuel cells (SOFC) consti ...
