  • Coherent structures and feedback control of wall turbulence 

    Vicenza, Fabio (Universitat Politècnica de Catalunya, 2010-09)
    Master thesis (pre-Bologna period)
    Restricted access - author's decision
    Turbulencia y fenómenos concomitantes como transferencia de calor, difusión, resistencia de fricción y ruido juegan un papel importante en los problemas industriales y ambientales. Desde el punto de vista de ahorro de ...
  • Low-frequency unsteadiness in the vortex formation region of a circular cylinder 

    Lehmkuhl Barba, Oriol; Rodríguez Pérez, Ivette María; Borrell Pol, Ricard; Oliva Llena, Asensio (2013-08-23)
    Article
    Open Access
    The presence of low-frequency fluctuations in the wake of bluff bodies have been observed in several investigations. Even though the flow past a circular cylinder at Re = 3900 (Re = U ref D/ν) has been the object of several ...
  • SAMPLER: An instrumentation project for studying the effect of turbulence in aquatic systems 

    Piera Fernández, Jaume; Quesada López, Rubén; Torrecilla Ribalta, Elena; Fernández, I.; Pons, S. (SARTI (Technological Development Centre of Remote Acquisition and Data processing Systems. Technical University of Catalonia (UPC)., 2005-10-01)

  • Study of the turbulent Prandtl number influence on the mixed convection heat transfer 

    Romeu Coscolla, Adrià (Universitat Politècnica de CatalunyaKarlsruher Institut für Technologie, 2013)
    Bachelor thesis
    Restricted access - author's decision
    The present study is a first insight into the world of Computational Fluid Dynamics (CFD)in power engineering. That is, numerical methods and algorithms are used to solve and analyze problems that involve heat and fluid ...
  • Subcritical equilibria in Taylor-Couette flow 

    Deguchi, Kengo; Meseguer Serrano, Álvaro; Mellibovsky Elstein, Fernando (2014-05-08)
    Article
    Open Access
    Nonlinear equilibrium states characterized by strongly localized vortex pairs are calculated in the linearly stable parameter region of counterrotating Taylor-Couette flow. These subcritical states are rotating waves whose ...
  • Turbulence structure of the atmospheric boundary layer in stable conditions 

    Rodríguez Cantalapiedra, Inma; Redondo Apraiz, José Manuel (2007)
    Conference report
    Open Access
    A partir de las mediciones de velocidad del aire, temperatura y humedad realizadas en la atmósfera en horario nocturno, se ha analizado la influencia de la estabilidad atmosférica en los flujos de momento y temperatura.
  • Turbulent natural convection in a differentially heated cavity of aspect ratio 5 filled with non-participating and participating grey media 

    Capdevila Paramio, Roser; Lehmkuhl Barba, Oriol; Trias Miquel, Francesc Xavier; Pérez Segarra, Carlos David; Colomer Rey, Guillem (2011)
    Conference lecture
    Restricted access - publisher's policy
    In the present work, turbulent natural convection in a tall differentially heated cavity of aspect ratio 5:1, filled with air (Pr = 0.7) under a Rayleigh number based on the height of 4.5 centerdot 1010, is studied ...
