  • A Chimera method for the incompressible Navier-Stokes equations 

    Houzeaux, Guillaume; Eguzkitza, Beatriz; Aubry, Romain; Owen, Herbert; Vázquez, Mariano (John Wiley & Sons, 2014-05-30)
    Article
    Open Access
    The Chimera method was developed three decades ago as a meshing simplification tool. Different components are meshed independently and then glued together using a domain decomposition technique to couple the equations ...
  • A low-dissipation finite element scheme for scale resolving simulations of turbulent flows 

    Lehmkuhl, Oriol; Houzeaux, Guillaume; Owen, Herbert; Chrysokentis, Giorgios; Rodríguez Pérez, Ivette María (2019-08-01)
    Article
    Restricted access - publisher's policy
    The present work extends the conservative convective scheme proposed by Charnyi et al. (2017) [13], originally formulated for mixed finite elements and tested in laminar flows, to equal order finite elements. A non-incremental ...

    Article
    Open Access
    A numerical assessment of different thermal conditions for an impinging flame configuration is investigated using large-eddy simulation. The cases of study correspond to a turbulent methane flame at equivalence ratio ER = ...
  • High-Performance Computing: Do’s and Dont’s 

    Houzeaux, Guillaume; Borrell, Ricard; Fournier, Yvan; Garcia-Gasulla, Marta; Göbbert, Jens H.; Hachem, Elie; Mehta, Vishal; Mesri, Youssef; Owen, Herbert; Vázquez, Mariano (InTech, 2018-02-14)
