  • MHD issues related to the use of Lithium Lead eutectic as breeder material for blankets of fusion power plants 

    Aiello, G.; Mistrangelo, C.; Buehler, L.; Mas de les Valls Ortiz, Elisabet; Aubert, J.-J.; Li-Puma, A.; Rapisarda, David; Del Nevo, A. (2015-04-01)
    Article
    Accés restringit per política de l'editorial
    The European Community is committed to the development of a DEMOnstration fusion power plant whose operation could start as soon as 2050. The blanket is one of the most critical components in a fusion reactor; three of the ...
  • Modelling of storage tanks with immersed heat exchangers 

    Cadafalch Rabasa, Jordi; Carbonell Sánchez, Daniel; Consul Serracanta, Ricard; Ruiz Mansilla, Rafael (2015-02-01)
    Article
    Accés restringit per política de l'editorial
    A model of a storage tank with an immersed serpentine heat exchanger is described and validated against experimental data available from the literature. The tank is modelled one dimensionally using the multi-node approach ...
  • An approach to verification and validation of MHD codes for fusion applications 

    Smolentsev, S.; Badia, Santiago; Bhattacharyayd, R.; Mas de les Valls Ortiz, Elisabet; Patel, A. (2015-11)
    Article
    Accés restringit per política de l'editorial
    We propose a new activity on verification and validation (V&V) of MHD codes presently employed by the fusion community as a predictive capability tool for liquid metal cooling applications, such as liquid metal blankets. ...
  • Mathematical models for tritium permeation analysis in liquid metal flows with helium bubbles 

    Batet Miracle, Lluís; Mas de les Valls Ortiz, Elisabet; Sedano Miguel, Luis Angel (2014-10-01)
    Article
    Accés restringit per política de l'editorial
    In LIBRETTO-2 test, evidence was obtained that helium bubbles nucleated and grew in the neutron irradiated PbLi probes. If such phenomenon occurs inside liquid metal (LM) breeding blanket channels, the study of its effect ...
  • Detailed modelling of flat plate solar thermal collectors with honeycomb-like transparent insulation 

    Cadafalch Rabasa, Jordi; Consul Serracanta, Ricard (2014-09-01)
    Article
    Accés restringit per política de l'editorial
    A detailed numerical model for flat-plate solar thermal collectors based on one-dimensional finite volume techniques was recently presented, see Cadafalch (2009). The model considers a solar thermal device as a pile of ...
  • Modelling of a supercritical CO2 power cycle for nuclear fusion reactors using RELAP5-3D 

    Batet Miracle, Lluís; Álvarez Fernández, Josep Maria; Mas de les Valls Ortiz, Elisabet; Martínez Quiroga, Víctor Manuel; Pérez Ferragut, Marina; Reventós Puigjaner, Francesc Josep; Sedano Miguel, Luis Angel (2014-04-01)
    Article
    Accés restringit per política de l'editorial
    A supercritical recompression CO2 power cycle has been simulated using the system code RELAP5-3D. This code is being developed by INL and has traditionally been used in the simulation of operational and accidental transients ...
  • From extruded-2D to fully-3D geometries for DNS: a multigrid-based extension of the Poisson solver 

    Gorobets, Andrei; Trias Miquel, Francesc Xavier; Soria Guerrero, Manel; Pérez Segarra, Carlos David; Oliva Llena, Asensio (2010)
    Article
    Accés restringit per política de l'editorial
    Direct numerical simulation (DNS) of incompressible flows is an essential tool for improving the understanding of the physics of turbulence and for the development of better turbulence models. The Poisson equation, the ...
  • DNS of turbulent natural convection flows on the MareNostrum supercomputer 

    Trias Miquel, Francesc Xavier; Gorobets, Andrei; Soria Guerrero, Manel; Oliva Llena, Asensio (2009)
    Article
    Accés restringit per política de l'editorial
    A code for the direct numerical simulation (DNS) of incompressible turbulent flows that provides a fairly good scalability for a wide range of computer architectures has been developed. The spatial discretization of the ...
