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.

    Torres Herrera, Ramon; Fayos Vallés, Francisco (2017-01-01)
    Article
    Accés restringit per política de l'editorial
    Different proposals for regular rotating black hole spacetimes have appeared recently in the literature. However, a rigorous analysis and proof of the regularity of this kind of spacetimes is still lacking. In this note ...

  • Using archives of past floods to estimate future flood hazards 

    Swierczynski, Tina; Ionita, Monica; Pino González, David (2017-01-13)
    Article
    Accés obert
    Worldwide, floods cause greater economic damage and loss of human life than any other type of natural disaster. We urgently need better assessments of flood hazards to reduce the societal impact of extreme floods caused ...
  • Inertial waves in rapidly rotating flows: a dynamical systems perspective 

    López Moscat, Juan Manuel; Marqués Truyol, Francisco (2016-11-02)
    Article
    Accés restringit per política de l'editorial
    An overview of recent developments in a wide variety of enclosed rapidly rotating flows is presented. Highlighted is the interplay between inertial waves, which have been predicted from linear inviscid considerations, and ...
  • 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 ...
