      Schillaci, Eugenio; Balcázar Arciniega, Néstor; Jofre Cruanyes, Lluís; Lehmkuhl Barba, Oriol; Castro González, Jesús (International Association for Computational Mechanics (IACM), 2014)
      Conference report
      Restricted access - publisher's policy
      The aim of this work is to propose and validate a numerical model that represents the hydrodynamic behavior of an Oscillating Water Column (OWC) device, that has been shown to be one of the most promising ways to extract ...
    • A level-set aided single-phase model for the numerical simulation of free-surface flow on unstructured meshes 

      Schillaci, Eugenio; Jofre Cruanyes, Lluís; Balcázar Arciniega, Néstor; Lehmkuhl, Oriol; Oliva Llena, Asensio (Elsevier, 2016-11-25)
      Article
      Open Access
      A new single-phase scheme for the numerical simulation of free-surface problems on 3-D unstructured meshes is presented. The flow field is obtained from the discrete solution of the incompressible Navier-Stokes equations, ...
    • A low-dissipation convection scheme for the stable discretization of turbulent interfacial flow 

      Schillaci, Eugenio; Jofre Cruanyes, Lluís; Balcázar Arciniega, Néstor; Antepara Zambrano, Óscar; Oliva Llena, Asensio (Elsevier, 2017-08-10)
      Article
      Open Access
      This paper analyzes a low-dissipation discretization for the resolution of immiscible, incompressible multiphase flow by means of interface-capturing schemes. The discretization is built on a three-dimensional, unstructured ...
    • A numerical study of liquid atomization regimes by means of conservative level-set simulations 

      Schillaci, Eugenio; Antepara Zambrano, Óscar; Balcázar Arciniega, Néstor; Rigola Serrano, Joaquim; Oliva Llena, Asensio (Elsevier, 2019-01-30)
      Article
      Open Access
      In this work, a conservative level-set finite-volume solver for interface-capturing is employed to perform the direct numerical simulation of Liquid Jets discharging into a quiescent air chamber. The scope is to propose a ...
    • Direct numerical simulation of multiphase flows with unstable interfaces 

      Schillaci, Eugenio; Lehmkuhl, Oriol; Antepara Zambrano, Óscar; Oliva Llena, Asensio (Institute of Physics (IOP), 2016-09-01)
      Article
      Open Access
      This paper presents a numerical model that intends to simulate efficiently the surface instability that arise in multiphase flows, typically liquid-gas, both for laminar or turbulent regimes. The model is developed on the ...
    • DNS of multiphase flows: study of atomization and free-surface phenomena 

      Schillaci, Eugenio (Universitat Politècnica de Catalunya, 2017-12-11)
      Doctoral thesis
      Open Access
      The present thesis focuses on the numerical analysis of some diverse physical set-up that involve the interaction of two -or three immiscible and incompressible phases. The simulations are carried out by means of finite-volume ...
    • Effectiveness of adaptive mesh refinement strategies in the DNS of multiphase flows 

      Schillaci, Eugenio; Antepara Zambrano, Óscar; Lehmkuhl Barba, Oriol; Balcázar Arciniega, Néstor; Oliva Llena, Asensio (Begell House, 2015)
      Conference report
      Restricted access - publisher's policy
      In this work, a finite-volume Adaptive Mesh Refinement (AMR) method for two phase flows able to dynamically achive the required mesh size in specific parts of the domain has been developed. The Navier-Stokes equations for ...
    • Numerical study of an impulse wave generated by a sliding mass 

      Schillaci, Eugenio; Favre Samarra, Federico; Antepara Zambrano, Óscar; Balcázar Arciniega, Néstor; Oliva Llena, Asensio (WIT Press, 2018)
      Article
      Open Access
      In this work, a numerical framework for the direct numerical simulation of tsunami waves generated by landslide events is proposed. The method, implemented on the TermoFluids numerical platform, adopts a free surface model ...
