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 ...
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 ...
Active flow control on airfoils by reinforcement learning
(Elsevier, 2023-11-05)
Active flow control is a widespread practice for airfoil aerodynamic performance enhancement. Within active flow control, reactive strategies are very effective, but the adequate design of these strategies is often complex. ...
CNN-based vane-type Vortex Generator modelling
(Taylor & Francis, 2024-01-05)
Computational Characterization Of The Vortex Generated By A Vortex Generator On A Flat Plate For Different Vane Angles
(Elsevier, 2017-06)
Vortex generators (VGs) are usually employed to improve the aerodynamic performance for both spatial or energy issues; such as aircrafts and wind turbine blades. These structures present poor aerodynamic performance in the ...
Flow control based 5 MW wind turbine enhanced energy production for hydrogen generation cost reduction
(2022-02-05)
Improving the performance and the production of renewable energy sources, especially the wind energy, is considered an attractive approach to reduce the Cost of Energy (COE) associated to the hydrogen generation process. ...
Numerical performance of CO2 accumulation and droplet dispersion from a cough inside a hospital lift under different ventilation strategies
(Nature, 2024)
The impact of mechanical ventilation on airborne diseases is not completely known. The recent pandemic of COVID-19 clearly showed that additional investigations are necessary. The use of computational tools is an advantage ...
Parametric study of low-profile vortex generators
(Elsevier, 2017-07-13)
Vortex generators (VGs) are flow control devices employed to avoid or delay flow separation. In most cases, the VG is calculated with the same height as the boundary layer (BL) thickness at the device position. However, ...
Performance enhancement of the artificial neural network– based reinforcement learning for wind turbine yaw control
(Wiley, 2019-11-03)
The yaw angle control of a wind turbine allows maximization of the power absorbed
from the wind and, thus, the increment of the system efficiency. Conventionally, classical
control algorithms have been used for the yaw ...
