  • An energy-preserving level set method for multiphase flows 

    Valle Marchante, Nicolás; Trias Miquel, Francesc Xavier; Castro González, Jesús (2020-01-01)
    Article
    Restricted access - publisher's policy
    The computation of multiphase flows presents a subtle energetic equilibrium between potential (i.e., surface) and kinetic energies. The use of traditional interface-capturing schemes provides no control over such a dynamic ...

    Green chemistry explores safer ways to prepare new materials from renewable resources. Thermosets are generally prepared from a mixture of monomers, with at least one of them having three or more reactive functions. This ...
  • Rheological and mechanical characterization of dual-curing thiol-acrylate-epoxy thermosets for advanced applications 

    Russo, Claudio; Fernández Francos, Xavier; Flor López, Sílvia de la (Multidisciplinary Digital Publishing Institute (MDPI), 2019-06-01)
    Article
    Open Access
    Mechanical and rheological properties of novel dual-curing system based on sequential thiol-acrylate and thiol-epoxy reactions are studied with the aim of addressing the obtained materials to suitable advanced applications. ...
  • Tailor-made thermosets obtained by sequential dual-curing combining isocyanate-thiol and epoxy-thiol click reactions 

    Gamardella, Francesco; Sabatini, Valentina; Ramis Juan, Xavier; Serra Albet, Maria Àngels (Elsevier, 2019-06-12)
    Article
    Restricted access - publisher's policy
    In this work, a new family of thermosets based on thiol-isocyanate-epoxy networks has been prepared via sequential dual-curing methodology where both reactions are activated by temperature. The sequential dual behaviour ...
  • Time-temperature-transformation (TTT) diagram of dual-curable epoxy thermosets obtained via two sequential epoxy-amine condensations 

    Konuray, Ali Osman; Salla Tarragó, José María; Morancho Llena, José María; Fernández Francos, Xavier; García Álvarez, Montserrat; Ramis Juan, Xavier (2019-08-01)
    Article
    Restricted access - publisher's policy
    A simple and robust strategy to generate time-temperature-transformation (TTT) diagrams for dual-curable thermosets is presented. TTT diagram is built for a dual-curable amine-epoxy formulation. Both curing stages are ...
  • Hard epoxy thermosets obtained via two sequential epoxy-amine condensations 

    Konuray, Ali Osman; García, Aina; Morancho Llena, José María; Fernández Francos, Xavier; Serra Albet, Maria Àngels; Ferrando Piera, Francesc; García Álvarez, Montserrat; Ramis Juan, Xavier (Elsevier, 2019-07-01)
    Article
    Restricted access - publisher's policy
    A new family of dual-curable poly(ß-hydroxyamine ether) thermosets based on amine-epoxy formulations has been prepared and characterized. Both curing stages consist in an epoxy-amine polycondensation, each having different ...
  • Improved environmental impact in the architecture industry: LCA analysis of an alternative masonry element 

    Szamosi, Zoltán; Szepesi, Gábor L.; Bodnár, István; Rosas Casals, Martí; Berényi, László (2019-09-26)
    Article
    Restricted access - publisher's policy
    The environmental performance of a building used for living or working depends to a large extent on its design and structure, but the total impact has additional influencing factors as well. The role of masonry elements ...
  • A dynamic load balancing method for the evaluation of chemical reaction rates in parallel combustion simulations 

    Muela Castro, Jordi; Borrell Pol, Ricard; Ventosa Molina, Jordi; Jofre Roca, Lluís; Lehmkuhl Barba, Oriol; Pérez Segarra, Carlos David (Elsevier, 2019-08-15)
    Article
    Restricted access - publisher's policy
    The development and assessment of an efficient parallelization method for the evaluation of reaction rates in combustion simulations is presented. Combustion simulations where the finite-rate chemistry model is employed ...
  • Effect of grain size and density of abrasive on surface roughness, material removal rate and acoustic emission signal in rough honing processes 

    Buj Corral, Irene; Álvarez Flórez, Jesús Andrés; Domínguez Fernandez, Alejandro (Multidisciplinary Digital Publishing Institute (MDPI), 2019-08-01)
    Article
    Open Access
    Honing processes provide a special cross-hatch pattern to the internal surface of cylinders that favors oil flow. However, along honing operation the abrasive grains wear out and lose their ability to cut material. The ...
  • Thermal and fluid dynamic analysis of Direct Steam Generation Parabolic Trough Collectors 

    Ferchichi, Souha; Kessentini, Hamdi; Morales Ruíz, Sergio; Rigola Serrano, Joaquim; Bouden, Chiheb; Oliva Llena, Asensio (Elsevier, 2019-09-15)
    Article
    Restricted access - publisher's policy
    Direct Steam Generation (DSG) has attracted considerable attention in comparison with conventional technologies based on Heat Transfer Fluids (HTF) for electricity generation due to its higher temperatures. In this context, ...
  • A level-set model for mass transfer in bubbly flows 

    Balcázar Arciniega, Néstor; Antepara Zambrano, Óscar; Rigola Serrano, Joaquim; Oliva Llena, Asensio (2019-08-01)
    Article
    Restricted access - publisher's policy
    A level-set model is presented for simulating mass transfer or heat transfer in two-phase flows. The Navier-Stokes equations and mass transfer (or heat transfer) equation are discretized using a finite volume method on a ...
