  • Bubble dynamics in turbulent duct flows: Lattice-Boltzmann simulations and drop tower experiments 

    Bitlloch, Pau; Ruiz Martí, Xavier; Ramírez de la Piscina Millán, Laureano; Casademunt Viader, Jaume (2018-06-23)
    Article
    Open Access
    Lattice-Boltzmann simulations of a turbulent duct flow have been carried out to obtain trajectories of passive tracers in the conditions of a series of microgravity experiments of turbulent bubble suspensions. The statistics ...
  • Experimental study of a microchannel bubble injector for microgravity applications 

    Arias Calderón, Santiago; Ruiz, X; Casademunt Viader, Jaume; Ramírez de la Piscina Millán, Laureano; González Cinca, Ricardo (2009-01)
    Article
    Restricted access - publisher's policy
    We perform a quantitative characterization of a microbubble injector in conditions relevant to microgravity. The injector pregenerates a slug flow by using a capillary T-junction, whose operation is robust to changes in ...
  • Generation and control of monodisperse bubble suspensions in microgravity 

    Bitlloch, Pau; Ruiz Martí, Xavier; Ramírez de la Piscina Millán, Laureano; Casademunt Viader, Jaume (2018-06-01)
    Article
    Open Access
    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 ...
  • Heat diffusion anisotropy in dendritic growth: phase field simulations and experiments in liquid crystals 

    González Cinca, Ricardo; Ramírez de la Piscina Millán, Laureano; Casademunt Viader, Jaume; Hernández Machado, Aurora; Toth-Katona, T; Börzsönyi, T; Buka, A (1998-10)
    Article
    Restricted access - publisher's policy
    An anisotropic heat diffusion coefficient is introduced in order to study some interfacial growth phenomena. This anisotropy has been incorporated in a phase field model which has been studied numerically to reproduce some ...
  • Pattern forming instabilities of the nematic smectic-B interface 

    Toth-Katona, T; Börzsönyi, T; Buka, A; González Cinca, Ricardo; Ramírez de la Piscina Millán, Laureano; Casademunt Viader, Jaume; Hernández-Manchado, A; Kramer, L (2000-10)
    Article
    Restricted access - publisher's policy
    Free growth properties of the smectic B liquid crystalline phase into the supercooled nematic have been investigated in quasi-two-dimensional geometry. Different orientation combinations of the two phases have been achieved ...
  • The role of connectivity and noise in the emergence of spontaneous activity in cultured neuronal networks 

    Gomez Orlandi, Javier; Álvarez Lacalle, Enrique; Teller Amado, Sara; Casademunt Viader, Jaume; Soriano Fradera, Jordi (2012-10)
    Article
    Open Access
    Cultured neurons in vitro quickly connect to one another to establish a spontaneously active network within a week. The resulting neuronal network is char- acterized by a combination of excitatory ...
  • 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
    Open Access
    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 ...
