  • 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
  • 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 ...
