  • Simultaneous measurement of neutron-induced capture and fission reactions at CERN 

    Guerrero, C.; Berthoumieux, Eric; Cano-Ott, D; Calviño Tavares, Francisco; Cortés Rossell, Guillem Pere; Gómez Hornillos, María Belén (2012)
    Article
    Open Access
    The measurement of the capture cross-section of fissile elements, of utmost importance for the design of innovative nuclear reactors and the management of nuclear waste, faces particular difficulties related to the -ray ...
  • Wind Shear and Buoyancy Reversal at the Top of Stratocumulus 

    Mellado González, Juan Pedro; Stevens, Bjorn; Schmidt, Heiko (2014-03-01)
    Article
    Open Access
    A numerical experiment is designed to study the interaction at the stratocumulus top between a mean vertical shear and the buoyancy reversal due to evaporative cooling, without radiative cooling. Direct numerical simulation ...
  • The Two-Layer Structure of the Entrainment Zone in the Convective Boundary Layer 

    Garcia, Jade; Mellado González, Juan Pedro (2014-06-01)
    Article
    Open Access
    The entrainment zone (EZ) of a dry, shear-free convective boundary layer growing into a linearly stratified fluid is studied by means of direct numerical simulation. The scale separation between the boundary layer thickness ...
  • Scaling Laws for the Heterogeneously Heated Free Convective Boundary Layer 

    van Heerwaarden, Chiel; Mellado González, Juan Pedro; de Lozar, Alberto (2014-11-01)
    Article
    Open Access
    The heterogeneously heated free convective boundary layer (CBL) is investigated by means of dimensional analysis and results from large-eddy simulations (LES) and direct numerical simulations (DNS). The investigated ...
  • Mixing driven by radiative and evaporative cooling at the stratocumulus top 

    de Lozar, Alberto; Mellado González, Juan Pedro (2015-12-01)
    Article
    Open Access
    The stratocumulus-top mixing process is investigated using direct numerical simulations of a shear-free cloud-top mixing layer driven by evaporative and radiative cooling. An extension of previous linear formulations ...
  • Experimentally well-constrained masses of 27P and 27S: implications for studies of explosive binary systems 

    Sun, Lijie; Xu, Xinxing; Hou, S.Q.; José Pont, Jordi (Elsevier, 2020-03-10)
    Article
    Open Access
    The mass of 27P is expected to impact the X-ray burst (XRB) model predictions of burst light curves and the composition of the burst ashes, but large uncertainties and inconsistencies still exist in the reported 27P masses. ...
  • Impact of thermally driven ocean turbulence on the melting of ice 

    Keitzl, Thomas; Mellado González, Juan Pedro; Notz, Dirk (2016-03-23)
    Article
    Open Access
    Direct numerical simulation and laboratory experiments are used to investigate turbulent convection beneath a horizontal ice–water interface. Scaling laws are derived that quantify the dependence of the melt rate of the ...
  • Global intermittency and collapsing turbulence in a stratified planetary boundary layer 

    Ansorge, Cedrick; Mellado González, Juan Pedro (2014-07-19)
    Article
    Open Access
  • Near-surface effects of free atmosphere stratification in free convection 

    Mellado González, Juan Pedro; van Heerwaarden, Chiel; Garcia, Jade (2016-04-01)
    Article
    Open Access
    The effect of a linear stratification in the free atmosphere on near-surface properties in a free convective boundary layer (CBL) is investigated by means of direct numerical simulation. We consider two regimes: a neutral ...
  • Polyamorphic transitions in Ce-based metallic glasses by synchrotron radiation 

    Duarte Correa, María Jazmín; Bruna Escuer, Pere; Pineda Soler, Eloi; Crespo Artiaga, Daniel; Garbarino, Gaston; Verbeni, Roberto; Zhao, Kun; Wang, Wei Hua; Romero Castro, Aldo Humberto; Serrano Gutiérrez, Jorge (2011-12-01)
    Article
    Open Access
    We report here on a polyamorphic-phase transition upon application of pressure on a Ce-based metallic glass, Ce70Al10Ni10Cu10, investigated by x-ray diffraction and inelastic x-ray scattering. This alloy is found to display ...
  • Growth and decay of a convective boundary layer over a surface with a constant temperature 

    van Heerwaarden, Chiel; Mellado González, Juan Pedro (2016-05-05)
    Article
    Open Access
    The growth and decay of a convective boundary layer (CBL) over a surface with a constant surface temperature that develops into a linear stratification is studied, and a mathematical model for this system is derived. The ...
  • Analysis of external and global intermittency in the logarithmic layer of Ekman flow 

    Ansorge, Cedrick; Mellado González, Juan Pedro (2016-10-25)
    Article
    Open Access
    Existence of non-turbulent flow patches in the vicinity of the wall of a turbulent flow is known as global intermittency. Global intermittency challenges the conventional statistics approach when describing turbulence ...
