    • Flow and turbulent structures around simplified car models 

      Aljure Osorio, David E.; Lehmkuhl Barba, Oriol; Rodríguez Pérez, Ivette María; Oliva Llena, Asensio (Elsevier, 2014-06-13)
      Article
      Open Access
      External car aerodynamics study has great importance in overall car efficiency and ride stability, being a key element in successful automotive design. The flow over car geometries shows three dimensional and unsteady ...
    • Flow over a realistic car model: wall modeled large eddy simulations assessment and unsteady effects 

      Aljure Osorio, David E.; Calafell Sandiumenge, Joan; Baez Vidal, Aleix; Oliva Llena, Asensio (2018-03-01)
      Article
      Open Access
      Numerical simulations are carried out on the flow over a realistic generic car geometry, the DrivAer-fastback car model. Pure large eddy simulations (LES) and wall-modeled large eddy simulations (WMLES) are used and compared ...
    • Influence of rotation on the flow over a cylinder at Re=5000 

      Aljure Osorio, David E.; Rodríguez Pérez, Ivette María; Lehmkuhl Barba, Oriol; Pérez Segarra, Carlos David; Oliva Llena, Asensio (2015-10-15)

      Conference lecture
      Open Access
      The aim of this paper is to carry out a group of numerical experiments over the fluid flow through a valve reed, using the CFD&HT code TermoFluids, an unstructured and parallel object-oriented CFD code for accurate and ...
    • On the IBM approximation for the wheel aerodynamic simulation 

      Aljure Osorio, David E.; Lehmkuhl Barba, Oriol; Martínez Valdivieso, Daniel; Favre Samarra, Federico; Oliva Llena, Asensio (2014)
      Conference report
