    This work is devoted to the study of turbulent natural convection flows in differentially heated cavities. The adopted configuration corresponds to an air-filled (Pr = 0.7) cavity of aspect ratio 5 and Rayleigh number Ra ...
  • Turbulent flow around a square cylinder at Reynolds number 22,000: A DNS study

    Accés restringit per política de l'editorial
    The turbulent flow around a square cylinder at Reynolds number 22,000 (based on the cylinder diameter and the inflow velocity) is studied by means of direct numerical simulation. An overview of the numerical methods and ...
  • Turbulent flow around a wall-mounted cube: direct numerical simulation and regularization modelling. 

    Trias Miquel, Francesc Xavier; Gorobets, Andrei; Verstappen, R.W.C.P.; Soria Guerrero, Manel; Oliva Llena, Asensio (2009)

    Since direct numerical simulation (DNS) cannot be performed at high Reynolds number, a dynamically less complex mathematical formulation is sought. In the quest for such formulation, we consider regularization (smooth ...
  • Turbulent flow in a differentially heated cavity: direct numérical simulation and regularization modeling

    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 ...
