• Experimental and numerical study of the wake behind a wing with a NACA0012 airfoil and comparison with theoretical models at moderate Reynolds numbers 

      Parras-Anguita, Luis; Domínguez-Vázquez, Adrián; Del-Pino-Peñas, Carlos Manuel (2014-09-24)
      Axial wing tip vortex characterization is a relevant issue not only from a theoretical point of view but also due to its interest in control engineering applications. An experimental study has been performed displacing a ...
    • Experimental characterization of wingtip vortices using smoke flow visualizations 

      Serrano-Aguilera, Juan José; García-Ortiz, José Hermenegildo; Gallardo-Claros, Alejandro; Parras-Anguita, Luis; Del-Pino-Peñas, Carlos Manuel (2016-07-20)
      In order to predict the axial development of the wingtip vortices strength an accurate theoretical model is required. Several experimental techniques have been used to that end, e.g. PIV or hotwire anemometry, but they ...
    • Nonlinear evolution of harmonically forced perturbations on a wingtip vortex 

      García-Ortiz, José Hermenegildo; Parras-Anguita, Luis; Diamessis, Peter; Del-Pino-Peñas, Carlos Manuel (2016-09-19)
      Wingtip vortices are created by flying airplanes due to lift generation. The vortex interaction with the trailing aircraft has sparked researchers’ interest to develop an efficient technique to destroy these vortices. ...
    • Numerical simulation of the buoyancy flow between two concentric cylinders with azimuthal variable heating 

      Medina Jiménez, Lucía; Serrano-Aguilera, Juan José; Blanco-Rodríguez, Francisco José; Parras-Anguita, Luis (Prof JP Meyer. Proceedings of the 15th International Conference on Heat Transfer, Fluid Mechanics and Thermodynamics (HEFAT2021), 2021-07-26)
      In this work, we present novel results of the buoyancy driven flow between two concentric cylinders, when an azimuthal thermal gradient is imposed to the inner cylinder. To accomplish that, angular-dependent temperature ...
    • On the optimaL response of q-vortex 

      Rodríguez-García, Jesús Óscar; Blanco-Rodríguez, Francisco José; Parras-Anguita, Luis; Del-Pino-Peñas, Carlos Manuel (2016-09-19)
      Wingtip vortices represent a hazard for the stability of the following airplane in airport highways. These flows have been usually modeled as swirling jets/wakes, which are known to be highly unstable and susceptible to ...
    • 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 (2019-07-18)
      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 ...
