  • 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 ...
  • 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 ...
  • Precession of a rapidly rotating cylinder flow: traverse through resonance 

    Marqués Truyol, Francisco; López Moscat, Juan Manuel (2015-10-06)
    Article
    Accés restringit per política de l'editorial
    Recent experiments using a rapidly rotating and precessing cylinder have shown that for specific values of the precession rate, aspect ratio and tilt angle, sudden catastrophic transitions to turbulence occur. Even if the ...
  • Numerical continuation methods for large-scale dissipative dynamical systems 

    Sánchez Umbría, Juan; Net Marcé, Marta (2016-11-22)
    Article
    Accés restringit per política de l'editorial
    A tutorial on continuation and bifurcation methods for the analysis of truncated dissipative partial differential equations is presented. It focuses on the computation of equilibria, periodic orbits, their loci of ...
  • A WRF simulation of an episode of contrails covering the entire sky 

    Mazón Bueso, Jordi; Pino González, David (2016-07-20)
    Article
    Accés obert
    On 21 September 2012 the entire sky was covered by contrails over the Gulf of Lyon (NW of the Mediterranean basin). These clouds were well recorded by ground observers as well as by Meteosat imagery. The atmospheric ...
