Battery Sizing Optimization in Power Smoothing Applications
(MDPI, 2022-01-19)
The main objective of this work was to determine the worth of installing an electrical battery in order to reduce peak power consumption. The importance of this question resides in the expensive terms of energy bills when ...
CNN-based flow control device modelling on aerodynamic airfoils
(Nature, 2022-06-17)
Wind energy has become an important source of electricity generation, with the aim of achieving a cleaner and more sustainable energy model. However, wind turbine performance improvement is required to compete with ...
Computational Modelling of Rectangular Sub-Boundary Layer Vortex Generators
(MDPI, 2018-01-19)
Vortex generators (VGs) are increasingly used in the wind turbine manufacture industry as flow control devices to improve rotor blade aerodynamic performance. Nevertheless, VGs may produce excess residual drag in some ...
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 ...
Automatic Identification Algorithm of Equivalent Electrochemical Circuit Based on Electroscopic Impedance Data for a Lead Acid Battery
(MDPI, 2021-06-06)
Obtaining tools to analyze and predict the performance of batteries is a non-trivial challenge because it involves non-destructive evaluation procedures. At the research level, the development of sensors to allow cell-level ...
Numerical Modeling of Face Shield Protection against a Sneeze
(MDPI, 2021-07-05)
The protection provided by wearing masks has been a guideline worldwide to prevent the risk of COVID-19 infection. The current work presents an investigation that analyzes the effectiveness of face shields as personal ...
A Battery Management System with EIS Monitoring of Life Expectancy for Lead–Acid Batteries
(MDPI, 2021-05-21)
Abstract
This work presents a battery management system for lead–acid batteries that integrates a battery-block (12 V) sensor that allows the online monitoring of a cell’s temperature, voltage, and impedance spectra. The ...
Robotic-Arm-Based Force Control by Deep Deterministic Policy Gradient in Neurosurgical Practice
(MDPI, 2023-09-30)
This research continues the previous work “Robotic-Arm-Based Force Control in Neurosurgical Practice”. In that study, authors acquired an optimal control arm speed shape for neurological surgery which minimized ...
