    During the last years, there has been a signi¿cant increment in the variety of hardware to overcome the power constraint in the context of the exascale challenge. This progress is leading to an increasing hybridisation of ...
  • On a physically-consistent nonlinear subgrid-scale heat flux model for LES of buoyancy driven flows 

    Trias Miquel, Francesc Xavier; Dabbagh, Firas; Gorobets, Andrei; Oliva Llena, Asensio (2018)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    Small-scale dynamics is the spirit of turbulence physics. It delivers complex mechanisms when turbulence is purely sustained by buoyancy. This takes place in Rayleigh-Bénard convection (RBC). Most of the existing RBC ...
  • An efficient two-layer wall model for high Reynolds number large eddy simulation
