      Accés restringit per política de l'editorial
      The fluid-structure interaction (FSI) problem has received great attention in the last few years, mainly because it is present in many physical systems, industrial applications, and almost every biological system. In the ...

    • Large-eddy simulations of the vortex-induced vibration of a low mass ratio two-degree-of-freedom circular cylinder at subcritical Reynolds numbers 

      Pastrana Maldonado, Daniel; Cajas García, Juan Carlos; Lehmkuhl Barba, Oriol; Rodríguez Pérez, Ivette María; Houzeaux, Guillaume (Elsevier, 2018-09)
      Article
      Accés obert
      The vortex induced vibration phenomenon of a low mass ratio () two-degree-of-freedom circular cylinder at subcritical Reynolds numbers ( 5300, 11,000) has been investigated by means of large-eddy simulations. A low-dissipative ...

    • On the formation of Taylor-Görtler structures in the vortex induced vibration phenomenon 

      Pastrana Maldonado, Daniel; Rodríguez Pérez, Ivette María; Cajas García, Juan Carlos; Lehmkuhl Barba, Oriol; Houzeaux, Guillaume (2020-06-01)
      Article
      Accés obert
      In this work, the three-dimensional structure of the boundary layer in the context of the vortex induced vibration of a circular cylinder is presented and investigated for the first time. Large-eddy simulations of a low ...

    • Vortex Induced Vibration (VIV) of circular cylinders at high Reynolds numbers 

      Pastrana Maldonado, Daniel; Cajas García, Juan Carlos; Lehmkuhl Barba, Oriol; Rodriguez, I.; Houzeaux, Guillaume (Barcelona Supercomputing Center, 2017-05-04)
      Text en actes de congrés
      Accés obert
      In this contribution, preliminary results on the study of the VIV at high Reynolds numbers are presented. First, a validation of the code and the turbulent LES WALE formulation in conjunction with a low-dissipative ...

    • Vortex induced vibrations of a pivoted finite height cylinder at low Reynolds number 

      Cajas García, Juan Carlos; Pastrana Maldonado, Daniel; Rodríguez Pérez, Ivette María; Lehmkuhl Barba, Oriol; Houzeaux, Guillaume; Vázquez, Mariano; Treviño Treviño, Cesar (2021-06-03)
      Article
      Accés obert
      The vortex induced vibrations (VIVs) of a pivoted cylinder with finite height have been numerically investigated. A mathematical model is introduced and described, and the resulting equations are numerically solved for low ...

    • Wakes and instabilities of static and freely vibrating cylinders 

      Rodríguez Pérez, Ivette María; Lehmkuhl Barba, Oriol; Pastrana Maldonado, Daniel; Cajas García, Juan Carlos; Houzeaux, Guillaume (Springer, 2019)
      Text en actes de congrés
      Accés obert
      The flow around static and freely vibrating cylinders are of interest in understanding different phenomena encountered in many practical applications.
