Assessing the statistical validity of momentum-deficit-based measurements in turbulent configurations
(Elsevier Ltd., 2021)
An application-agnostic procedure is outlined for checking the validity of momentum-deficit-based drag measurements performed under different turbulent conditions in a wind tunnel. The approach defines a two-step methodology: ...
Experimental assessment of scale-effects on the aerodynamic characterization of a transitionally-operating airfoil working under clean flow conditionsExperimental assessment of scale-effects on the aerodynamic characterisation of a transitionally-operating airfoil working under clean flow conditions
(Elsevier, 2022)
Wind tunnel tests are carried out upon a NACA0021 airfoil subjected to transitional Reynolds numbers. Transitionally-operating airfoils show a high sensitivity to external conditions and pose relevant measurement issues ...
A holistic optimization tool for the design of power take-off systems in realistic wave climates: The Wells turbine case
(Elsevier, 2023)
The growing demand of energy coupled with the worldwide commitments in favor of renewable technologies turns marine renewable sources especially attractive, including wave energy. In particular, the oscillating water column ...
Industria eolikoko palen efizientzia aerodinamikoaren azterketa esperimentala baldintza ideal eta errealetan
(UEU, 2021)
The paradigm of renewable energies brings a number of challenges to be solved in a short-term period. In the case of wind energy, it turns necessary to relocate onshore wind-farms in both offshore coastal regions and urban ...
A proper orthogonal decomposition analysis upon aerodynamic structures under clean and rough conditions
(AIP Publishing, 2023)
A transitional flow regime is known to induce complex flow structures upon aerodynamic geometries such as airfoils, and the dynamics of laminar separation bubbles (LSBs) pose a relevant research field. In addition to being ...
Impact of turbulence and blade surface degradation on the annual energy production of small-scale wind turbines
(Wiley, 2023)
Small-scale horizontal axis wind-turbines (SHAWTs) are acquiring relevance withinthe regulatory policies of the wind sector aiming at net-zero emissions, while reduc-ing visual and environmental impact by means of distributed ...
Techno-economic assessment of far-offshore hydrogen-carrying energy vectors off the Iberian Peninsula
(Elsevier, 2024)
Green hydrogen (H2) generation in far-offshore locations is being proposed as an alternative for the decarbonisation of the current fossil fuel-based energy system. However, due to the limited experience and low level of ...
Benchmarking of spectral methods for fatigue assessment of mooring systems and dynamic cables in offshore renewable energy technologies
(Elsevier, 2024)
Fatigue life estimation methods based on time-domain and rainflow counting techniques are widely recognised and accepted for their reliability. However, applying them in scenarios involving random loads with multiple ...
