Computational Modelling of Three Different Sub-Boundary Layer Vortex Generators on a Flat Plate
(MDPI, 2018-11-10)
Flow separation is the source of several problems in a wind turbine including load fluctuations, lift losses, and vibrations. Vortex generators (VGs) are passive flow control devices used to delay flow separation, but their ...
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 ...
