    • A reduced-dissipation WENO scheme with automatic dissipation adjustment 

      Fernández-Fidalgo, Javier; Ramírez, Luis; Tsoutsanis, Panagiotis; Colominas, Ignasi; Nogueira, Xesús (Elsevier, 2020)
      [Abstract:] In this paper, we propose a novel modification to the WENO-family schemes to reduce its intrinsic dissipation. In this work, we focus on the WENO5 scheme, which is rewritten in terms of a central plus a dissipative ...

    • Improved δ-SPH Scheme With Automatic and Adaptive Numerical Dissipation 

      Krimi, Abdelkader; Ramírez, Luis; Khelladi, Sofiane; Navarrina, Fermín; Deligant, Michaël; Nogueira, Xesús (MDPI, 2020)
      [Abstract] In this work we present a δ-Smoothed Particle Hydrodynamics (SPH) scheme for weakly compressible flows with automatic adaptive numerical dissipation. The resulting scheme is a meshless self-adaptive method, in ...
