A Parametric Study of Trailing Edge Flap Implementation on Three Different Airfoils Through an Artificial Neuronal Network
(MDPI, 2020-05-18)
Trailing edge flaps (TEFs) are high-lift devices that generate changes in the lift and drag coefficients of an airfoil. A large number of 2D simulations are performed in this study, in order to measure these changes in ...
The Sailor diagram – A new diagram for the verification of two-dimensional vector data from multiple models
(Copernicus Gesellschaft, 2020-07-15)
A new diagram is proposed for the verification of vector quantities generated by multiple models against a set of observations. It has been designed with the objective, as in the Taylor diagram, of providing a visual ...
Combining random forests and physics-based models to forecast the electricity generated by ocean waves: A case study of the Mutriku wave farm
(Pergamon-Elsevier, 2019-10-01)
This paper combines random forests with physics-based models to forecast the electricity output of the Mutriku wave farm on the Bay of Biscay. The period analysed was 2014-2016, and the forecast horizon was 24 h in 4-h ...
Global estimations of wind energy potential considering seasonal air density changes
(Pergamon-Elsevier, 2019-11-15)
The literature typically considers constant annual average air density when computing the wind energy potential of a given location. In this work, the recent reanalysis ERA5 is used to obtain global seasonal estimates of ...
Problem-Based Learning in University Studies on Renewable Energies: Case of a Laboratory Windpump
(MDPI, 2020-03-23)
In the last eight years, the new faculty of Engineering in Renewable Energies at the University of the Basque Country in Eibar has developed several sustainability goals related to clean energy and climate change, but also ...
Long-term changes in offshore wind power density and wind turbine capacity factor in the Iberian Peninsula (1900–2010)
(Elsevier, 2021-03-23)
This study analysed temporal and spatial changes in offshore wind power density (WPD) and capacity factor (CF) around the Iberian Peninsula during the 20th century by analysing data from ERA20 and ERA5. Both WPD and CF ...
The power flow and the wave energy flux at an operational wave farm: Findings from Mutriku, Bay of Biscay
(Elservier, 2021-04-14)
Mutriku is a wave farm on the Spanish coast of the Bay of Biscay that has now been continuously supplying electricity for more than nine years. Since 1979, there has been a growing trend in wave energy flux for the whole ...
Seasonal Correction of Offshore Wind Energy Potential due to Air Density: Case of the Iberian Peninsula
(MDPI, 2019-07-02)
A constant value of air density based on its annual average value at a given location is commonly used for the computation of the annual energy production in wind industry. Thus, the correction required in the estimation ...
The Consequences of Air Density Variations over Northeastern Scotland for Offshore Wind Energy Potential
(MDPI, 2019-07-09)
Hywind-Scotland is a wind farm in Scotland that for many reasons is at the leading edge of technology and is located at a paradigmatic study area for offshore wind energy assessment. The objective of this paper is to compute ...
