      Bitlloch, Pau; Ruiz Martí, Xavier; Ramírez de la Piscina Millán, Laureano; Casademunt Viader, Jaume (2018-06-01)
      Article
      Accés obert
      A new experimental setup for the generation of homogeneous, monodisperse bubble suspensions in turbulent duct flows in microgravity has been designed and tested in drop tower experiments. The setup provides independent ...
    • 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
      Accés obert
      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 ...

      Accés restringit per decisió de l'autor
      Realitzat a/amb:   Karlsruher Institut für Technologie
      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
      Accés obert
      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 ...

      Text en actes de congrés
      Accés obert
      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 bubble jets in microgravity : spatial despersion and velocity fluctuation 

      Bitlloch, Pau; Ruiz Martí, Xavier; Ramírez de la Piscina Millán, Laureano; Casademunt Viader, Jaume (2015-06-01)
      Article
      Accés obert
      A detailed statistical analysis of bubble dispersion in turbulent jets based on data from drop tower experiments is presented here. A stochastic model is also introduced in order to capture these statistics to a large ...
