Aerodynamic characterization of transitionally-operating airfoils under a set of flow conditions going from ideal to real configurations
Zarketa-Astigarraga, Ander (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
Zarketa-Astigarraga, Ander; Martin-Mayor, Alain; Martinez Agirre, Manex; Penalba, Markel (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: ... -
