  • Building proper invariants for eddy-viscosity subgrid-scale models 

    Trias Miquel, Francesc Xavier; Folch, David; Gorobets, Andrei; Oliva Llena, Asensio (2015-06-23)
    Article
    Open Access
    Direct simulations of the incompressible Navier-Stokes equations are limited to relatively low-Reynolds numbers. Hence, dynamically less complex mathematical formulations are necessary for coarse-grain simulations. ...
  • Spectrally-consistent regularization of turbulent Rayleigh-Bénard convection 

    Dabbagh, Firas; Trias Miquel, Francesc Xavier; Gorobets, Andrei; Oliva Llena, Asensio (International Association for Computational Mechanics (IACM), 2014)
    Conference report

    Direct numerical simulation (DNS) of turbulent Rayleigh-Bénard convection in an air filled (Pr = 0,7) rectangular cell of squared cross-section with periodic boundary conditions in the span-wise direction, has been carried ...
  • Turbulent flow around a square cylinder at Reynolds number 22,000: A DNS study 

    Trias Miquel, Francesc Xavier; Gorobets, Andrei; Oliva Llena, Asensio (Elsevier, 2015-12-21)
    Article
    Restricted access - publisher's policy
    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 ...
