  • Energy-preserving stable computations of high-pressure supercritical fluids turbulence 

    Ollé Bernades, Marc; Capuano, Francesco; Trias Miquel, Francesc Xavier; Jofre Cruanyes, Lluís (2022)
    Conference report
    Open Access
    High-fidelity computations of turbulent flows at high-pressure supercritical fluid conditions present significant challenges. Besides the inherent broadband nature of the flow, the rapid variation of thermophysical properties ...

  • Study of the conservation properties in two-way coupled dispersed multiphase flows using finite volume methods 

    Bahramian, Linda; Muela Castro, Jordi; Pérez Segarra, Carlos David (Institute of Physics (IOP), 2021)
    Conference lecture
    Open Access
    In order to simulate dispersed multiphase flows, the coupling level must be determined according to the volume fraction in the system. The volume fraction is the ratio of the total volume of the dispersed phases over the ...

  • DNS of Mass Transfer in Bi-dispersed Bubble Swarms 

    Balcázar Arciniega, Néstor; Rigola Serrano, Joaquim; Oliva Llena, Asensio (2022)
    Conference report
    Restricted access - publisher's policy
    This work presents Direct Numerical Simulation of mass transfer in a bi-dispersed bubble swarm at high Reynolds number, by using a multiple marker level-set method. Transport equations are discretized by the finite-volume ...

  • MAGICA project: development of a Multi-frequency Automotive GNSS Integrated Cost effective Antenna 

    Filatov, Evgenii; Vélez, Marco Antonio; Gemio, Joan; Vicente, Jose Javier; Capdevila Paramio, Roser; Tantinyà, Laura; Gil, Alberto; Cardalda, Adrián; Baños, Daniel; Mogas, Pere; Reyes, Joaquín (2021)
    Conference report
    Open Access
    The present work describes the Multi-frequency Automotive GNSS Integrated Cost-effective Antenna (MAGICA) project and the first results. This is a two years project that started in August 2020 under the sponsorship of the ...

  • Numerical Investigation on fluid flow of protruding branching duct in a dividing junction of a minichannel heat exchanger 

    Settati, Mohamed; Oliet Casasayas, Carles; Oliva Llena, Asensio (2021)
    Conference report
    Open Access
    This study focuses on investigating the effect of protruding branching duct on laminar fluid field in 90¿ dividing pipe junction of mini heat exchanger. The ducts under study, main and branch side, are of minichannel scale ...

  • DNS of unequal size droplets collision using a moving-mesh/level-set method 

    Amani, Ahmad; Balcázar Arciniega, Néstor; Gutierrez, Enrique; Oliva Llena, Asensio (Springer, 2019)
    Conference report
    Restricted access - publisher's policy
    The dynamics of binary droplets collision is of huge importance in different fields, from multiphase reactors (Dudukovic et al in Chem Eng Sci 54:1975–1995, 1999 [11]), raindrop formation, ink-jet printing, spray combustion, ...

  • DNS of Drag-Force and Reactive Mass Transfer in Gravity-Driven Bubbly Flows 

    Balcázar Arciniega, Néstor; Antepara Zambrano, Óscar; Rigola Serrano, Joaquim; Oliva Llena, Asensio (Springer, 2019)
    Conference report
    Restricted access - publisher's policy
    Mass transfer processes in bubbly flows are relevant in both nature and industry. Multiple examples arise from the so-called unit operations of the chemical engineering, where bubble columns are used for separation processes, ...

  • A GPU Accelerated Framework for Partitioned Solution of Fluid-Structure Interaction Problems 

    Totounferoush, Amin; Naseri, Alireza; Chiva Segura, Jorge; Oliva Llena, Asensio; Mehl, Miriam (2021)
    Conference report
    Open Access
    We present a GPU-accelerated solver for the partitioned solution of fluid-structure interaction (FSI) problems. Independent scalable fluid and structure solvers are coupled by a library which handles the inter-code data ...

  • Paving the (right) way for DNS and LES on unstructured grids: (fully) conservative collocated/staggered discretizations 

    Trias Miquel, Francesc Xavier; Gorobets, Andrei; Oliva Llena, Asensio (2021)
    Conference report
    Restricted access - publisher's policy
    The essence of turbulence are the smallest scales of motion. They result from a subtle balance between convective transport and diffusive dissipation. Mathematically, these terms are governed by two differential operators ...

  • Symmetry-preserving discretization of Navier-Stokes on unstructured grids: collocated vs staggered 

    Trias Miquel, Francesc Xavier; Valle Marchante, Nicolás; Gorobets, Andrei; Oliva Llena, Asensio (2021)
    Conference report

  • On a Proper Tensorial Subgrid Heat Flux Model 

    Trias Miquel, Francesc Xavier; Dabbagh, Firas; Santos Serrano, Daniel; Gorobets, Andrei; Oliva Llena, Asensio (2021)
    Conference report
    Open Access
    In this work, we aim to shed light to the following research question: can we find a nonlinear tensorial subgrid-scale (SGS) heat flux model with good physical and numerical properties, such that we can obtain satisfactory ...
