• Effect of the axial jet on the optimal response in Batchelor vortex 

      Blanco-Rodriguez, Maria Jose; García-Ortiz, J. Hermenegildo; Parras-Anguita, Luis; Del-Pino-Peñas, Carlos Manuel (2015-09-25)
      En este póster se estudia la respuesta óptima del torbellino de Batchelor para distintos números de onda. Se demuestra que incluso teniendo la velocidad axial, un torbellino es capaz de tener grandes amplificaciones de energía.
    • Influence of Reynolds number on theoretical models for trailing vortices 

      Domínguez-Vázquez, Adrián; García-Ortiz, J. Hermenegildo; Serrano Aguilera, Juan José; Parras-Anguita, Luis; Del-Pino-Peñas, Carlos Manuel (2015-07-09)
      We conduct direct numerical simulations for a NACA0012 airfoil at Reynolds numbers (Re) ranging from 300 to 7000 to determine the wake behavior behind this wing profile. We characterize the structure of the wing-tip vortex, ...
    • Wingtip vortex in a NACA0012 airfoil and its active control 

      García-Ortiz, J. Hermenegildo; Blanco-Rodriguez, Maria Jose; Parras-Anguita, Luis; Del-Pino-Peñas, Carlos Manuel (2015-09-09)
      We conduct experiments in a towing-tank to analyse the flow patterns of wingtip vortices in a NACA 0012 airfoil. In this experimental research, we provide PIV measurements and flow visualisations. Without active control, ...
