    A nonlinear model predictive control (NMPC) for the thermal management (TM) of Plug-in Hybrid Electric Vehicles (PHEVs) is presented. TM in PHEVs is crucial to ensure good components performance and durability in all ...

  • Conceptual design of the EU-DEMO dual coolant lithium lead equatorial module 

    Rapisarda, David; Fernández, I.; Palermo, I.; González, M.; Moreno Sierra, César; Moreno, C.; Mas de les Valls Ortiz, Elisabet (2016-09-01)
    Article
    Accés obert
    Within the framework of EUROfusion Program, the Dual Coolant Lithium Lead (DCLL) is one of the four EU breeder blanket concepts that are being investigated as candidates for DEMO. DCLL uses PbLi as the main coolant, tritium ...

  • 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 obert
    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 obert
    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 ...
