  • Effect of land cover and climate changes on rainfall-induced landslides: regional-scale modelling in the Val d’Aran (Pyrenees, Spain) 

    Hurlimann Ziegler, Marcel; Medina Iglesias, Vicente César de; Lloret Morancho, Antonio; Vaunat, Jean; Puig i Polo, Càrol; Moya Sánchez, José (International Society for Soil Mechanics and Geotechnical Engineering (ISSMGE), 2021)
    Conference report
    Open Access
    The analysis of the impacts of future environmental changes on rainfall-induced landslides is of great importance. Recent studies have shown that these changes will affect the frequency and magnitude of shallow slides and ...

  • Effect of the actuation on the boundary layer of an airfoil at moderate reynolds number 

    Lehmkuhl, Oriol; Rodríguez Pérez, Ivette María; Borrell Pol, Ricard (Springer, 2020)
    Conference report
    Restricted access - publisher's policy
    Synthetic (zero net mass flux) jets are an active flow control technique to manipulate the flow field in wall-bounded and free-shear flows. The fluid necessary to actuate on the boundary layer is intermittently injected ...

  • Wakes and instabilities of static and freely vibrating cylinders 

    Rodríguez Pérez, Ivette María; Lehmkuhl, Oriol; Pastrana Maldonado, Daniel; Cajas García, Juan Carlos; Houzeaux, Guillaume (Springer, 2019)
    Conference report
    Restricted access - publisher's policy
    The flow around static and freely vibrating cylinders are of interest in understanding different phenomena encountered in many practical applications.

  • Assessment of LES techniques for mitigating the Grey Area in DDES models 

    Pont Vilchez, Arnau; Santos Serrano, Daniel; Trias Miquel, Francesc Xavier; Duben, Alexey; Revell, Alistair; Oliva Llena, Asensio (2019)
    Conference report
    Open Access
    The slow RANS-LES transition is a well-known shortcoming in hybrid turbulence models such as DelayedDetached Eddy Simulation (DDES). The present work assesses the feasibility of 2D sensitive LES models for naturally ...

  • Improving DES capabilities for predicting Kelvin-Helmholtz instabilities. Comparison with a backward-facing step DNS. 

    Pont Vilchez, Arnau; Trias Miquel, Francesc Xavier; Duben, Alexey; Revell, Alistair; Oliva Llena, Asensio (2020-05-10)
    Conference report
    Restricted access - publisher's policy
    The Detached Eddy Simulation (DES) turbulence model presented by Spalart et al. (Comments on the Feasibility of LES for Wings, and on a Hybrid RANS/LES Approach, [1]) in the late 90s, was specifically designed to simulate ...

  • Exploring the performance of a miniature 3D wind sensor under extreme martian winds up to the dust devil scale 

    Domínguez Pumar, Manuel; Kowalski, Lukasz; Jiménez Serres, Vicente; Rodríguez Pérez, Ivette María; Soria Guerrero, Manel (2019)
    Conference report
    Open Access
    The objective of this paper is to explore the performance of a miniature 3D spherical wind sensor for Mars atmosphere, working under extreme wind speeds, up to the Dust Devil scale. The experimental campaign has been made ...

    Aguilar Plazaola, José Agustín; Husar, Attila Peter (2019)
    Conference report
    Open Access
    This work introduces our ongoing research in developing accurate models for predicting and analyzing Proton-Exchange Membrane Fuel Cells performance. An initial model, whose response is compared with experimental data is ...

  • On the Feasibility of CFD for Transient Air Flow Simulations in Buildings 

    Morozova, Nina; Capdevila Paramio, Roser; Trias Miquel, Francesc Xavier; Oliva Llena, Asensio (2019)
    Conference report
    Restricted access - publisher's policy
    The rapidly growing computational capacity hasmade CFD simulations an attractive tool for indoorenvironmental applications. The ability of CFD toperform transient simulations could be incorporatedinto model predictive ...

    Conference report
    Open Access
    Solid Oxide Elecyrolizers (SOEC) are electrochemical devises that produce hydrogen from water using the energy of an electric power source. SOEC operate at high temperatures (around 800ºC) and have efficiencies around 53% ...

  • Load profile effect on durability of proton exchange membrane fuel cells 

    Aguilar Plazaola, José Agustín; Husar, Attila Peter (2019)
    Conference report
    Open Access
    Proton Exchange Membrane Fuel Cells (PEMFC) are a promising technology for substitution of hydrocarbon powerdrives and battery based electrical supply systems. However, below-required durability is still an important factor ...
