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 ...
Theoretical Concepts for Describing a Replication-levels-based Uncertainty Analysis Approach
(International Frequency Sensor Association IFSA, 2021)
Aerodynamic characterization of transitionally-operating airfoils under a set of flow conditions going from ideal to real configurations
(Mondragon Unibertsitatea. Goi Eskola Politeknikoa, 2021)
Applications in which airfoils operate under transitional flow conditions are widespread, comprising micro- and nano-aerial-vehicle wings, portions of mid- and large-scale wind-turbine blades or turbomachinery vanes. The ...
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 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 ...
A holistic optimization tool for the design of power take-off systems in realistic wave climates: The Wells turbine case
(Elsevier, 2023)
The growing demand of energy coupled with the worldwide commitments in favor of renewable technologies turns marine renewable sources especially attractive, including wave energy. In particular, the oscillating water column ...
On the Definition of a Comprehensive Technology-Informed Accessibility Metric for Offshore Renewable Energy Site Selection
(MDPI, 2023)
Despite the important role of offshore renewable energies (OREs) in the energy transition, the economical viability is still unclear. Therefore, an appropriate site selection is crucial. Besides the energy potential, the ...
