    • Localized pinning states in closed containers: homoclinic snaking without bistability 

      Mercader Calvo, María Isabel; Batiste Boleda, Oriol; Alonso Maleta, María Aránzazu; Knobloch, Edgar (2009-08)
      Article
      Accés obert
      Binary mixtures with a negative separation ratio are known to exhibit time-independent spatially localized convection when heated from below. Numerical continuation of such states in a closed two-dimensional container with ...

    • Natural convection in a horizontal cylinder with axial rotation 

      Sánchez Casals, Odalys de la Caridad; Mercader Calvo, María Isabel; Batiste Boleda, Oriol; Alonso Maleta, María Aránzazu (AMER PHYSICAL SOC, 2016-06-23)
      Article
      Accés obert
      We study the problem of thermal convection in a laterally heated horizontal cylinder rotating about its axis. A cylinder of aspect ratio Gamma = H/2R = 2 containing a small Prandtl number fluid (sigma = 0.01) representative ...

    • Numerical simulation of the genesis of superhighway convection in a slightly inclined layer of a binary liquid mixture 

      Alonso Maleta, María Aránzazu; Mercader Calvo, María Isabel; Batiste Boleda, Oriol (2015)
      Text en actes de congrés
      Accés obert
      Convection in a fluid layer is affected by its orientation with respect to the gravitational field. In the present work, we investigate numerically pattern selection in a vertical cylindrical cell heated from below for ...

    • On the determination of diffusion coefficients in two-component alloys and doped semiconductors: several implications concerning the International Space Station 

      Sánchez Meneses, O.; Ruiz Martí, Xavier; Pujalte, Mónica; Mercader Calvo, María Isabel; Batiste Boleda, Oriol; Gavaldà, Josefina (2015-07-01)
      Article
      Accés obert
      The accurate determination of mass diffusion coefficients is a technologically relevant problem that has implications on the modelling and control of material processes such as crystal growth and casting. It is also important ...

    • Pattern selection near the onset of convection in binary mixtures in cylindrical cells 

      Alonso Maleta, Arantxa; Mercader Calvo, María Isabel; Batiste Boleda, Oriol (2014-08-01)
      Article
      Accés obert
      We report numerical investigations of three-dimensional pattern formation of binary mixtures in a vertical cylindrical container heated from below. Negative separation ratio mixtures, for which the onset of convection ...

    • Secondary flows in a laterally heated horizontal cylinder 

      Mercader Calvo, María Isabel; Sánchez Casals, Odalys de la Caridad; Batiste Boleda, Oriol (2014-01-01)
      Article
      Accés obert
      In this paper we study the problem of thermal convection in a laterally heated, finite, horizontal cylinder. We consider cylinders of moderate aspect ratio (height/diameter approximate to 2) containing a small Prandtl ...

    • Stationary localized solutions in binary convection in slightly inclined rectangular cells
