Computational Characterization of a Rectangular Vortex Generator on a Flat Plate for Different Vane Heights and Angles
(MDPI, 2019-03-01)
Vortex generators (VG) are passive flow control devices used for avoiding or delaying the separation of the boundary layer by bringing momentum from the higher layers of the fluid towards the surface. The Vortex generator ...
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 ...
Microtab design and implementation on a 5MW wind turbine
(MDPI, 2017-05-24)
Microtabs (MT) consist of a small tab placed on the airfoil surface close to the trailing edge and perpendicular to the surface. A study to find the optimal position to improve airfoil aerodynamic performance is presented. ...
Power Control Optimization of an Underwater Piezoelectric Energy Harvester
(MDPI, 2018-03)
Over the past few years, it has been established that vibration energy harvesters with intentionally designed components can be used for frequency bandwidth enhancement under excitation for sufficiently high vibration ...
5 MW Wind Turbine Annual Energy Production Improvement by Flow Control Devices
(MDPI, 2018-11-06)
Several flow control devices have been studied in recent years. Majority of them were designed firstly for aeronautical purposes. At present many research is aimed to introduce these devices in wind turbines (WTs) in order ...
Gurney Flap Implementation on a DU91W250 Airfoil
(MDPI, 2018-11-06)
Abstract
The increasing capability of Wind Turbine (WT) based power generation systems has derived in an increment of the WT rotor diameter, i.e., longer rotor blades. This results in an increase of the electrical power ...
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 ...
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 ...
