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: ... -
Experimental assessment of scale-effects on the aerodynamic characterization 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 application
(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 ... -
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 ... -
State of the art of small wind energy analysing different controls
(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 ...
