Aquesta línia de recerca té com a objectiu estudiar la dinàmica de règims preturbulents o de turbulència plenament desenvolupada. Per extensió, s'estudien problemes associats amb la dinàmica no lineal d'ones, sistemes complexos, formació d'estructures dissipatives (patterns), etc. La major part dels problemes objecte d'estudi corresponen a sistemes d'interès geofísic o de recerca bàsica, és a dir, oceanografia, dinàmica atmosfèrica, dinàmica mediambiental, però també són objecte d'estudi alguns models matemàtics d'interès físic o biològic susceptibles de propagar ones, fronts, polsos, defectes, etc. Com a exemple de problemes en estudi podem esmentar la convecció tèrmica, la turbulència en fluids estratificats, els sistemes en rotació, la dinàmica de mescles, l'arrossegament de sediments, els corrents de gravetat, etc. Quant a les tècniques que s'utilitzen, en el camp de la teoria es combina la simulació numèrica directa de processos amb tècniques analítiques de reducció a formes normals, equacions d'amplitud, dinàmica caòtica, etc. En el terreny experimental, la tècnica més emprada és el tractament digital d'imatges de fluxos obtinguts en experiments de laboratori.

  • Flexible rod design for educational wind balance 

    Raush Alviach, Gustavo Adolfo; Castilla López, Roberto; Gámez Montero, Pedro Javier; Wojciechowski, Jakub; Codina Macià, Esteban (2016-03-07)
    Article
    Accés obert
    This article provides a technical description of a flexible hinge for wind tunnel rigs. For academic purposes, the device was integrated into several rod flexures to build a home-made external wind balance system. The ...
  • The potential of the sea breeze for wind energy generation in peri-urban coastal areas using small wind turbines 

    Rojas Gregorio, José Ignacio; Cabrera Agudo, Barbara; Mazón Bueso, Jordi (2016)
    Text en actes de congrés
    Accés obert
    This work investigates the potential of the sea breeze for wind energy generation with small wind turbines. For this purpose, we used wind data recorded in the Llobregat Delta (NE of the Iberian Peninsula) from 1993 to ...
  • Periodic orbits in tall laterally heated rectangular cavities 

    Net Marcé, Marta; Sánchez Umbría, Juan (2017-02-02)
    Article
    Accés obert
    This study elucidates the origin of the multiplicity of stable oscillatory flows detected by time integration in tall rectangular cavities heated from the side. By using continuation techniques for periodic orbits, it is ...
  • Maxwell equations in the Debye potential formalism 

    Fayos Vallés, Francisco; Llanta Salleras, Estanislao; Llosa, J (1985-02-01)
    Article
    Accés obert
    The authors propose a method for computing the electromagnetic test-field created by a given distribution of charges and currents using the Debye potential formalism in curved space-times. This framework has been applied ...
  • Nonlinear and detuning effects of the nutation angle in precessionally-forced rotating cylinder flow 

    Lopez Moscat, Juan Manuel; Marqués Truyol, Francisco (2016-06-16)
    Article
    Accés obert
    The flow in a rapidly rotating cylinder forced to precess through a nutation angle a is investigated numerically, keeping all parameters constant except a, and tuned to a triadic resonance at a = 1º. When increasing a, ...
  • An exactly solvable model in P.R.M.: quantization. II 

    Iranzo Fernández, Vicente; Llosa, J; Marqués Truyol, Francisco; Molina, A (1984-01)
    Article
    Accés obert
    The quantization of a priori hamiltonian predictive systems is studied. It is applied to quantize the family of N-particle relativistic models presented in ref. 1. The relativistic two-particle oscillator is studied in ...
  • Are the Pyrenees a barrier for the transport of birch (Betula) pollen from Central Europe to the Iberian Peninsula? 

    Izquierdo Miguel, Rebeca; Alarcón Jordán, Marta; Mazón Bueso, Jordi; Pino González, David; De Linares, Concha; Aguinagalde, Xabier; Belmonte Soler, Jordina (2017-01-01)
    Article
    Accés obert
    This work provides a first assessment of the possible barrier effect of the Pyrenees on the atmospheric transport of airborne pollen from Europe to the North of the Iberian Peninsula. Aerobiological data recorded in three ...
  • Km-scale shoreline sand waves in the Western Mediterranean Sea 

    Falqués Serra, Albert; Ribas Prats, Francesca (Springer International Publishing, 2017)
    Capítol de llibre
    Accés restringit per política de l'editorial
    A number of morphodynamic models have been developed to simulate the dynamics of large-scale bedform patterns on the continental shelf. Most of the models are based on linear stability analysis and, therefore, only ...
