Experimental uncertainty decompositions of aerodynamic coefficients affected by operative condition variations
(Elsevier Ltd., 2020)
A twofold analysis is performed on an experimental set-up comprising a low-Reynolds wind tunnel, with the aim of quantifying the effect of measurand uncertainties and operative condition variations in the lift and drag ...
Assessing the statistical validity of momentum-deficit-based measurements in turbulent configurations
(Elsevier Ltd., 2021)
An application-agnostic procedure is outlined for checking the validity of momentum-deficit-based drag measurements performed under different turbulent conditions in a wind tunnel. The approach defines a two-step methodology: ...
State of the art of small wind energy analysing different controlsEstado del arte de la energía minieólica analizando diferentes controles
(Dyna, 2022)
Existen dos topologías de aerogeneradores según el eje de giro: eje horizontal, "Horizontal Axis Wind turbines" (HAWT) y de eje vertical, "Vertical Axis Wind Turbines" (VAWT) [2]. Las turbinas HAWT son empleadas para ...
Experimental assessment of scale-effects on the aerodynamic characterization of a transitionally-operating airfoil working under clean flow conditionsExperimental assessment of scale-effects on the aerodynamic characterisation of a transitionally-operating airfoil working under clean flow conditions
(Elsevier, 2022)
Wind tunnel tests are carried out upon a NACA0021 airfoil subjected to transitional Reynolds numbers. Transitionally-operating airfoils show a high sensitivity to external conditions and pose relevant measurement issues ...
Experimental comparative study between MPPT, hybrid P&O and fuzzy control for a small wind turbine applicationEstudio comparativo experimental entre MPPT, P&O híbrido y un control basado en lógica difusa para una comparación experiemental de minieólica
(Federacion de Asociaciones de Ingenieros Industriales de Espana, 2021)
This study focuses on a comparison between different maximum power extraction controls for a small wind turbine application. In this case, a vertical axis wind turbine (VAWT) coupled to a permanent magnet synchronous ...
