  • Modeling circulation patterns induced by spatial cross-shore wind variability in a small-size coastal embayment 

    Cerralbo Peñarroya, Pablo; Espino Infantes, Manuel; Grifoll Colls, Manel (2016-08)
    Article
    Accés restringit per política de l'editorial
    This contribution shows the importance of the cross-shore spatial wind variability in the water circulation in a small-sized micro-tidal bay. The hydrodynamic wind response at Alfacs Bay (Ebro River delta, NW Mediterranean ...
  • A new equilibrated residual method improving accuracy and efficiency of flux-free error estimates 

    Parés Mariné, Núria; Díez, Pedro (2017-01-01)
    Article
    Accés obert
    This paper presents a new methodology to compute guaranteed upper bounds for the energy norm of the error in the context of linear finite element approximations of the reaction–diffusion equation. The new approach revisits ...
  • A distortion measure to validate and generate curved high-order meshes on CAD surfaces with independence of parameterization 

    Gargallo Peiró, Abel; Roca Navarro, Xevi; Peraire Guitart, Jaume; Sarrate Ramos, Josep (John Wiley & Sons, 2016-06)
    Article
    Accés restringit per política de l'editorial
    A framework to validate and generate curved nodal high-order meshes on Computer-Aided Design (CAD) surfaces is presented. The proposed framework is of major interest to generate meshes suitable for thin-shell and 3D finite ...
  • Concurrent finite element simulation of quadrupolar and dipolar flow noise in low Mach number aeroacoustics 

    Guasch Fortuny, Oriol; Pont Ribas, Arnau; Baiges Aznar, Joan; Codina, Ramon (Elsevier, 2016-07)
    Article
    Accés restringit per política de l'editorial
    The computation of flow-induced noise at low Mach numbers usually relies on a two-step hybrid methodolgy. In the first step, an incompressible fluid dynamics simulation (CFD) is performed and an acoustic source term is ...
  • IberWQ: new simulation tool for 2D water quality modelling in rivers and shallow estuaries 

    Cea Gómez, Luis; Puertas Agudo, Jerónimo; Bladé i Castellet, Ernest; Escolano Tercero, Enrique; Bermúdez Hermida, Marta María (2016-09)
    Article
    Accés restringit per política de l'editorial
    This paper presents a new freeware simulation tool (IberWQ) for 2D water quality modelling in rivers and non-stratified estuaries. The model computes the spatial and temporal evolution of several species and variables which ...
  • Canal monitoring algorithm 

    Soler Guitart, Joan; Gómez Valentín, Manuel; Bonet Gil, Enrique (2016-03)
    Article
    Accés obert
    One of the main problems in the water management of irrigation canals is the control of water distribution among users’ outlets. This is because of the difficulty of measuring the removing flows correctly because they are ...
  • Observation of two-dimensional spatial solitary waves in a ¿ (2) medium 

    Torruellas, William; Stegeman, George; Torner Sabata, Lluís (IEEE Press, 1995)
    Text en actes de congrés
    Accés obert
    Cascaded second order nonlinear processes offer a new range of opportunities. Indeed we have shown that under near phase matching conditions, the associated nonlinear phase distortion to the fundamental wave depletion ...
  • Study of resonant modes in a 700 nm pitch macroporous silicon photonic crystal 

    Cardador Maza, David; Vega Bru, Didac; Segura Garcia, Daniel; Rodríguez Martínez, Ángel (2017-01-01)
    Article
    Accés obert
    In this study the modes produced by a defect inserted in a macroporous silicon (MP) photonic crystal (PC) have been studied theoretical and experimentally. In particular, the transmitted and reflected spectra have been ...
  • Evolución de la microestructura de un suelo limoso compactado a lo largo de trayectorias hidro-mecánicas 

    Mora Ortiz, René Sebastián; Ismael Baptista, Elías Abdul; Romero Morales, Enrique Edgar (2014)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    La microestructura, entendida como la distribución del tamaño de poros, es una propiedad importante que condiciona el comportamiento de los suelos compactados y que permite explicar los cambios importantes que se detectan ...
  • Turbulent separated shear flow control by surface plasma actuator: experimental optimization by genetic algorithm approach 

    Benard, N.; Pons Prats, Jordi; Periaux, Jacques Francis; Bugeda Castelltort, Gabriel; Braud, P.; Bonnet, J.P.; Moreau, E. (2016-02)
    Article
    Accés restringit per política de l'editorial
    The potential benefits of active flow control are no more debated. Among many others applications, flow control provides an effective mean for manipulating turbulent separated flows. Here, a nonthermal surface plasma ...
