  • 3M en pantalla (mitos y mentiras sobre metales en pantalla) 

    Salán Ballesteros, Maria Núria; Montalà Guitart, Francesc; Sureda Anfres, Miquel (Sociedad Española de Materiales, 2020-05)
    Article
    Open Access
    Los metales han formado parte de la evolución de la humanidad desde la antigüedad. Han sido objeto de culto, por escasos y exclusivos, y han sido la clave del desarrollo de armas, para, progresivamente, formar parte de los ...
  • Aeroelastic analysis of parachute deceleration systems with empirical aerodynamics 

    Ortega, Enrique; Flores Le Roux, Roberto Maurice (2019-11-13)
    Article
    Open Access
    A technique for the aeroelastic solution of parachute decelerators is presented in this work. The methodology uses empirical aerodynamics, based on a filling-time inflation model and Ludtke's area law, coupled to two ...
  • Efficient aeroelastic analysis of inflatable structures using enhanced potential flow aerodynamics 

    Ortega, Enrique; Flores Le Roux, Roberto Maurice; Cuartero Zaragoza, Eric; Oñate Ibáñez de Navarra, Eugenio (2019-10)
    Article
    Restricted access - publisher's policy
    An efficient method for the aeroelastic analysis of wind effects on inflatable structures is presented. The solution scheme is staggered and uses an explicit finite-element structural solver and potential flow aerodynamics. ...
  • On the exploitation of differential aerodynamic lift and drag as a means to control satellite formation flight 

    Traub, Constantin; Romano, Francesco; Binder, Tilman; García-Almiñana, Daniel; Rodríguez Donaire, Silvia; Sureda Anfres, Miquel (springer-Verlag, 2019-05-27)
    Article
    Open Access
    For a satellite formation to maintain its intended design despite present perturbations (formation keeping), to change the formation design (reconfiguration) or to perform a rendezvous maneuver, control forces need to be ...
  • An implicit unsteady hydraulic solver for suspended cuttings transport in managed pressure wells 

    Flores Le Roux, Roberto Maurice; Ortega, Enrique; Ilin, A.; Simpkins, Douglas; Oñate Ibáñez de Navarra, Eugenio (Springer, 2019-04)
    Article
    Open Access
    We present a simulation tool for transient events in complex hydraulic networks. The code includes modelling of the transport of suspended cuttings in near-vertical wells. An unstructured finite volume formulation with ...
  • Geosynchronous inclined orbits for high-latitude communications 

    Fantino, Elena; Flores Le Roux, Roberto Maurice; Di Carlo, Marilena; Di Salvo, Alessio; Cabot Soler, Elisenda (2017-11-01)
    Article
    Open Access
    We present and discuss a solution to the growing demand for satellite telecommunication coverage in the high-latitude geographical regions (beyond 55°N), where the signal from geostationary satellites is limited or ...
  • Nonlinear loads model for harmonics flow prediction, using multivariate regression 

    Lamich Arocas, Manuel; Balcells Sendra, Josep; Corbalán Fuertes, Montserrat; Griful Ponsati, Eulàlia (Institute of Electrical and Electronics Engineers (IEEE), 2017-06)
    Article
    Open Access
    This paper describes a method for obtaining a model of a single or a set of nonlinear loads (NLL) connected to a certain point of an electrical network. The basic assumption is that the network supplying the NLL has ...
  • Influence of data resolution in nonlinear loads model for harmonics prediction 

    Balcells Sendra, Josep; Lamich Arocas, Manuel; Griful Ponsati, Eulàlia; Corbalán Fuertes, Montserrat (2016)
    Article
    Open Access
    This paper describes the influence of data resolution in the agreement of models to predict harmonics generated by nonlinear loads (NLL), basically formed by single phase and three phase rectifiers, eventually combined ...
  • A-posteriori error estimation for the finite point method with applications to compressible flow 

    Ortega, Enrique; Flores Le Roux, Roberto Maurice; Oñate Ibáñez de Navarra, Eugenio; Idelsohn Barg, Sergio Rodolfo (2017-04)
    Article
    Open Access
    An a-posteriori error estimate with application to inviscid compressible flow problems is presented. The estimate is a surrogate measure of the discretization error, obtained from an approximation to the truncation terms ...
  • In situ particle zeta potential evaluation in electroosmotic flows from time-resolved microPIV measurements 

    Sureda Anfres, Miquel; Miller, Andrew; Diez, F. J. (2012-09-10)
    Article
    Restricted access - publisher's policy
    A time-resolved microPIV method is presented to measure in an EOF the particles zeta potential in situ during the transient start-up of a microdevice. The method resolves the electrophoretic velocity of fluoro-spheres used ...
  • Ram-air parachute simulation with panel methods and staggered coupling 

    Ortega, Enrique; Flores Le Roux, Roberto Maurice; Pons Prats, Jordi (2016-09-07)
    Article

  • Reliability versus mass optimization of CO2 extraction technologies for long duration missions 

    Detrell Domingo, Gisela; Griful Ponsati, Eulàlia; Messerschmid, Ernst (2016-06-01)
    Article
    Open Access
    The aim of this paper is to optimize reliability and mass of three CO2 extraction technologies/components: the 4-Bed Molecular Sieve, the Electrochemical Depolarized Concentrator and the Solid Amine Water Desorption. The ...
