    • Large eddy simulation and laboratory experiments on the decay of grid wakes in strongly stratified flows 

      Fraunie, P.; Chashechkin, Y.; Redondo Apraiz, José Manuel; Velasco Montes, David; Rayo Berreba, S. (2009-07-27)
      Article
      Accés obert
      A detailed analysis of the flow structure resulting from the combination of turbulence and internal waves is carried out and visualized by means of the Schlieren method on waves in a strongly stratified fluid at the ...
    • MicroHH 1.0: a computational fluid dynamics code for direct numerical simulation and large-eddy simulation of atmospheric boundary layer flows 

      van Heerwaarden, Chiel; van Stratum, Bart; Heus, Thijs; Gibbs, Jeremy; Fedorovich, Evgeni; Mellado González, Juan Pedro (2017-08-28)
      Article
      Accés obert
      This paper describes MicroHH 1.0, a new and open-source (www.microhh.org) computational fluid dynamics code for the simulation of turbulent flows in the atmosphere. It is primarily made for direct numerical simulation but ...
    • On the dynamics of the turbulent flow past a three-element wing 

      Montalà Sales, Ricard; Lehmkuhl Barba, Oriol; Rodríguez Pérez, Ivette María (2024-02-12)
      Article
      Accés obert
      A comprehensive analysis of the unsteady flow dynamics past the 30P30N three-element high lift wing is performed by means of large eddy simulations at different angles of attack (AoA=5°, 9°, and 23°) and at a Reynolds ...
    • Regularization modeling of wall-bounded turbulent flows 

      Trias Miquel, Francesc Xavier; Gorobets, Andrei; Verstappen, R.W.C.P.; Oliva Llena, Asensio (2010)
      Comunicació de congrés
      Accés restringit per política de l'editorial
      Since direct numerical simulations cannot be computed at high Reynolds numbers, a dynamically less complex formulation is sought. In the quest for such a formulation, we consider regularizations of the convective term ...
    • Towards stochastic methods in CFD for engineering applications 

      Tosi, Riccardo (Universitat Politècnica de Catalunya, 2021-12-21)
      Tesi
      Accés obert
      Recent developments of high performance computing capabilities allow solving modern science problems employing sophisticated computational techniques. However, it is necessary to ensure the efficiency of state of the art ...
    • Turbulent flow in a differentially heated cavity: direct numérical simulation and regularization modeling 

      Trias Miquel, Francesc Xavier; Gorobets, Andrei; Oliva Llena, Asensio; Verstappen, R.W.C.P. (2010)
      Comunicació de congrés
      Accés restringit per política de l'editorial
      We consider regularizations of the convective term that preserve symmetry and conservation properties exactly. This yields a novel class of regularizations that restrain the convective production of small scales in an ...
