    • VOF/Navier-Stokes implementation on 3D unstructured staggered meshes. Application to the Richtmyer-Meshkov instability 

      Jofre Cruanyes, Lluís; Lehmkuhl Barba, Oriol; Castro González, Jesús; Oliva Llena, Asensio (2011)
      Comunicació de congrés
      Accés restringit per política de l'editorial
      The numerical simulation of interfacial and free surface flows is a vast and interesting topic in the areas of engineering and fundamental physics, such as the study of liquid-gas interfaces, formation of droplets, bubbles ...

    • 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.

    • Wall resolved large eddy simulations of a three-element high-lift airfoil at different angles of attack 

      Montalà Sales, Ricard; Lehmkuhl Barba, Oriol; Rodríguez Pérez, Ivette María (European Research Community on Flow, Turbulence, and Conbustion (ERCOFTAC), 2023)
      Text en actes de congrés
      Accés obert
      A parametric study of the flow past the 30P30N three-element high-lift wing is conducted by changing the angle of attack (α = 5, 9 and 23◦) at a constant Reynolds number (Rec = 750, 000). Computational predictions are ...

    • Wall‐modeled large‐eddy simulation in a finite element framework 

      Owen, Herbert; Chrysokentis, Georgios; Avila, Matias; Mira Martínez, Daniel; Houzeaux, Guillaume; Cajas, Juan Carlos; Lehmkuhl Barba, Oriol (Wiley, 2020-01)
      Article
      Accés obert
      This work studies the implementation of wall modeling for large‐eddy simulation in a finite element context. It provides a detailed description of how the approach used by the finite volume and finite differences communities ...
