Generation and control of monodisperse bubble suspensions in microgravity
(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 ... -
Low-frequency unsteadiness in the vortex formation region of a circular cylinder
(2013-08-23)
Article
Accés obertThe 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 ... -

Spectrally-consistent regularization modeling at very high Rayleigh numbers
(Begell House, 2012)
Text en actes de congrés
Accés restringit per política de l'editorialThe incompressible Navier-Stokes equations constitute an excellent mathematical modelization of turbulence. Unfortunately, attempts at performing direct simulations are limited to relatively low-Rayleigh numbers because ... -

(Université de Poitiers, 2012)
Text en actes de congrés
Accés obertThe incompressible Navier-Stokes equations constitute an excellent mathematical modelization of turbulence. Unfortunately, attempts at performing direct simulations are limited to relatively low-Reynolds numbers because ... -
Spectrally-consistent regularization modeling of wind farm boundary layers
(2012)

Study of the turbulent Prandtl number influence on the mixed convection heat transfer
(Universitat Politècnica de Catalunya / Karlsruher Institut für Technologie, 2013)
Treball Final de Grau
Accés restringit per decisió de l'autor
Realitzat a/amb: Karlsruher Institut für TechnologieThe 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
(2014-05-08)
Article
Accés obertNonlinear 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 ... -
Turbulence structure of the atmospheric boundary layer in stable conditions
(2007)
Text en actes de congrés
Accés obertA 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
(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 ... -
Turbulent natural convection in a differentially heated cavity of aspect ratio 5 filled with non-participating and participating grey media
(2011)
Comunicació de congrés
Accés restringit per política de l'editorialIn the present work, turbulent natural convection in a tall differentially heated cavity of aspect ratio 5:1, filled with air (Pr = 0.7) under a Rayleigh number based on the height of 4.5 centerdot 1010, is studied ... -
