    • A first study on an oscillatory flow enclosed in a finite cylinder 

      Panadès i Guinart, Carles (Universitat Politècnica de Catalunya, 2009-09-14)
      Master thesis
      Open Access
      In this preliminar work, an oscillatory flow contained in a closed cylinder is investigated by means of spectral methods. The problem is quite related with the Stokes boundary layer and the major phenomena belong to this ...
    • Convecció tèrmica amb rotació : efectes centrífugs 

      Zambrana Puyalto, Xavier (Universitat Politècnica de Catalunya, 2008-07-01)
      Minor thesis
      Open Access
    • Dinàmica d'ions a la magnetosfera de la Terra 

      Contreras Molina, Gerard (Universitat Politècnica de Catalunya, 2020-07)
      Bachelor thesis
      Open Access
      En aquest treball s'explora el problema de Störmer. Aquest tracta de l'estudi de les trajectòries dels ions en influència del camp magnètic terrestre. S'ha dut a terme a partir de l'expressió del lagrangià de la partícula ...
    • Infinite period bifurcation due to imperfections in rotating thermal convection 

      López Alonso, Jose Manuel (Universitat Politècnica de Catalunya, 2011-06-17)
      Master thesis
      Open Access
      A pinning area is a band of finite width where rotating waves with precession frequences near zero turn into steady non-axisymmetric solutions. Dynamical systems theory suggests that any imperfection breaking the SO(2) ...
    • Non-linear fluid dynamics in oscillatory cylindrical cavities 

      Panadès i Guinart, Carles (Universitat Politècnica de Catalunya, 2013-06-28)
      Doctoral thesis
      Open Access
      Even though the transition to turbulence has been studied for over a century, its complete comprehension still remains unclear even for the simplest flows and continues to be a daunting challenge for the scientific community. ...
    • Numerical modeling of simple laboratory experiments of rotating flows 

      López Alonso, José Manuel (Universitat Politècnica de Catalunya, 2015-02-05)
      Doctoral thesis
      Open Access
      Despite the large amount of research which has been conducted on turbulent flows, a full understanding of their dynamics as well as the mechanisms involved in the onset of turbulence is still missing. Experimental studies ...
    • Simulació bidimensional d’un sistema de boies per extreure energia del mar 

      Camps Santasmasas, Marta (Universitat Politècnica de Catalunya, 2010-02-09)
      Master thesis
      Open Access
      L’objectiu d’aquest treball és modelitzar i estudiar el comportament d’un sistema format per una plataforma flotant amb diverses boies situat a alta mar que té per objectiu extreure energia de l’onatge incident. Per tal ...
