    Doctoral thesis
    Open Access
    En la tesis doctoral Convección térmica en un anillo cilíndrico en rotación se estudian diferentes aspectos de la dinámica lineal y no lineal de un fluido Boussinesqconfinado en un anillo cilíndrico, en rotación alrededor ...
  • Convectons 

    Alonso Maleta, María Aránzazu; Batiste Boleda, Oriol; Knobloch, Edgar; Mercader Calvo, María Isabel (Springer, 2011-01-01)
    Part of book or chapter of book
    Open Access
    A horizontal layer containing a miscible mixture of two fluids can generate dissipative solitons called convectons when heated from below. The physics of the system leading to this behavior is explained, and the properties ...
  • Convectons, anticonvectons and multiconvectons in binary fluid convection 

    Mercader Calvo, María Isabel; Batiste Boleda, Oriol; Alonso Maleta, María Aránzazu; Knobloch, Edgar (2011-01-25)
    Article
    Open Access
    Binary fluid mixtures with a negative separation ratio heated from below exhibit steady spatially localized states called convectons for supercritical Rayleigh numbers. Numerical continuation is used to compute such states ...

    Mercader Calvo, María Isabel; Batiste Boleda, Oriol; Alonso Maleta, María Aránzazu; Knobloch, Edgar (2009-12-21)
    Article
    Restricted access - publisher's policy
    Numerical continuation is used to compute spatially localized convection in a binary fluid with no-slip laterally insulating boundary conditions and the results are compared with the corresponding ones for periodic boundary ...

    A horizontal layer containing a miscible mixture of two fluids can produce dissipative solitons when heated from below. The physics of the system is described, and dissipative solitons are computed using numerical continuation ...
  • Effect of small inclination on binary convection in elongated rectangular cells 

    Mercader Calvo, María Isabel; Batiste Boleda, Oriol; Alonso Maleta, María Aránzazu; Knobloch, Edgar (American Institute of Physics (AIP), 2019-02-26)
    Article
    Open Access
    We analyze the effect of a small inclination on the well-studied problem of two-dimensional binary fluid convection in a horizontally extended closed rectangular box with a negative separation ratio, heated from below. The ...
  • 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
    Open Access
    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

    Article
    Open Access
    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)
    Conference report
    Open Access
    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 ...
