    Direct numerical simulations (DNS) of the incompressible Navier-Stokes equations are limited to relatively low-Reynolds numbers. Therefore, dynamically less complex mathematical formulations are necessary for coarse-grain ...
  • On the blending of regularization and large-eddy simulation 

    Folch, David; Trias Miquel, Francesc Xavier; Gorobets, Andrei; Oliva Llena, Asensio (International Association for Computational Mechanics (IACM), 2014)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    Direct simulations of the incompressible Navier-Stokes equations at high Reynolds numbers are not feasible because the convective term produces far too many relevant scales of motion. Therefore, in the foreseeable future, ...
  • On the evolution of flow topology in turbulent Rayleigh-Bénard convection

    Article
    Accés obert
    Small-scale dynamics is the spirit of turbulence physics. It implicates many attributes of flow topology evolution, coherent structures, hairpin vorticity dynamics, and mechanism of the kinetic energy cascade. In this work, ...
