  • A short note on a 3D spectral analysis for turbulent flows on unstructured meshes 

    Tsoutsanis, Panagiotis; Nogueira, Xesús; Fu, Lin (Elsevier, 2023)
    [Abstract:] We propose two techniques for computing the energy spectra for 3D unstructured meshes that are consistent across different element types. These techniques can be particularly useful when assessing the dissipation ...
  • A simple model for mixing intuition and analysis 

    Katsikopoulos, Konstantinos V.; Egozcue, Martin; Fuentes García, Luis (Elsevier, 2022)
    [Abstract:] Firefighters, emergency paramedics, and airplane pilots are able to make correct judgments and choices in challenging situations of scarce information and time pressure. Experts often attribute such successes ...
  • UCNS3D: An open-source high-order finite-volume unstructured CFD solver 

    Antoniadis, Antonis F.; Drikakis, Dimitris; Farmakis, Pericles S.; Fu, Lin; Kokkinakis, Ioannis; Nogueira, Xesús; Silva, Paulo A.S.F.; Skote, Martin; Titarev, Vladimir; Tsoutsanis, Panagiotis (Elsevier, 2022)
    [Abstract:] UCNS3D is an open-source computational solver for compressible flows on unstructured meshes. State-of-the-art high-order methods and their associated benefits can now be implemented for industrial-scale CFD ...
  • An Arbitrary Lagrangian-Eulerian SPH-MLS Method for the Computation of Compressible Viscous Flows 

    Ramírez, Luis; Eirís, Antonio; Couceiro, Iván; París, José; Nogueira, Xesús (Elsevier, 2022)
    [Abstract] In this work we present a high-accurate discretization to solve the compressible Navier-Stokes equations using an Arbitrary Lagrangian-Eulerian meshless method (SPH-MLS), which can be seen as a general formulation ...
  • Krein’s theorem in the context of topological abelian groups 

    Borsich, Tayomara; Domínguez, Xabier; Martín Peinador, Elena (MDPI, 2022)
    [Abstract:] A topological abelian group G is said to have the quasi-convex compactness property (briefly, qcp) if the quasi-convex hull of every compact subset of G is again compact. In this paper we prove that there exist ...
