Theoretical parameters of trailing vortices versus aspect ratio of wing models Aguilar-Cabello, Jorge Jiménez-Rodríguez, Alberto Parras-Anguita, Luis Del-Pino-Peñas, Carlos Manuel Mecánica de fluidos We perform 2D-PIV measurements to characterize trailing vortices in NACA0012 wing models for aspect ratios ranging between 1 and 2.5, and for chord-based Reynolds numbers from 7000 to 40000. Firstly, and regarding the influence of the Reynolds number, the increase of this dimensionless parameter generates a more concentrated and intense vortex, presenting, therefore, an increase in all its characteristic magnitudes: maximum azimuthal velocity and vorticity. Secondly, the greater the aspect ratio, the greater the vortex strength is observed. Thirdly, the radial location of the peak of the azimuthal velocity has a strong decay as the aspect ratio increases for Re=7000, but it changes its trend for Re=40000. 2019-07-18T10:10:11Z 2019-07-18T10:10:11Z 2019 2019-07-18 conference output https://hdl.handle.net/10630/18076 eng Workshop on Fluid Mechanics Granada 22/07/2019 open access
