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
Accés obertLattice-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 ... -
Controlled generation of vapor/liquid slug flows by local boiling in microgravity
Bitlloch, Pau; Ruiz Martí, Xavier; Ramírez de la Piscina Millán, Laureano; Casademunt Viader, Jaume (2020-09-01)
Article
Accés obertWe design, construct, and test a device for controlled boiling by means of local vapor bubble formation in a cavity that injects vapor bubbles in a capillary crossflow. The outcome of the device is a regular slug flow of ... -
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
Accés obertA 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 ... -

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 obertThe 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 ... -
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 obertA 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 ...
