    Article
    Open Access
    La industria avícola mundial genera una gran cantidad de residuos que en la actualidad son mayoritariamente desechados. Entre ellos, las plumas (CFs), estructuras queratínicas que presentan grupos funcionales y otras ...

  • Fluid dynamics and heat transfer in the wake of a sphere 

    Rodríguez Pérez, Ivette María; Lehmkuhl, Oriol; Soria Guerrero, Manel; Gómez, Samuel; Domínguez Pumar, Manuel; Kowalski, Lukasz (2019-04)
    Article
    Restricted access - publisher's policy
    Direct numerical simulation and large-eddy simulation have been performed for a heated sphere at Reynolds numbers of $Re=1000$ and $Re=10^4$, respectively. The Prandtl number for both simulations has been $Pr=0.7$. ...

  • Active flow control for external aerodynamics: from micro air vehicles to a full aircraft in stall 

    Lehmkuhl, Oriol; Lozano-Durán, Adrian; Rodríguez Pérez, Ivette María (Institute of Physics (IOP), 2020-04-01)
    Article
    Open Access
    We investigate the aerodynamic performance of active flow control of airfoils and wings using synthetic jets with zero net-mass flow. The study is conducted via wall-resolved and wall-modeled large-eddy simulation using ...

  • 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

    The flow around static and freely vibrating cylinders are of interest in understanding different phenomena encountered in many practical applications.

  • Effects of the actuation on the boundary layer of an airfoil at Reynolds Number Re = 60000 

    Rodríguez Pérez, Ivette María; Lehmkuhl, Oriol; Borrell Pol, Ricard (Springer-Verlag, 2020-05-29)
    Article
    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 present paper focuses on the role of the periodic actuation mechanisms on the ...

  • Click-based dual-curing thermosets and their applications 

    Ramis Juan, Xavier; Fernández Francos, Xavier; Flor López, Sílvia de la; Ferrando Piera, Francesc; Serra Albet, Maria Àngels (Elsevier, 2018)
    Part of book or chapter of book

    Dual curing is the methodology for obtaining thermosets by combining two different and compatible polymerization reactions, taking place sequentially or simultaneously. Sequential dual-curing processing enables the preparation ...

  • 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 ...

  • Versatile image-based measurements of granular flows and water wave propagation in experiments of tsunamis generated by landslides 

    Bregoli, Francesco; Medina Iglesias, Vicente César de; Bateman Pinzón, Allen (2020-04-01)
    Article
    Open Access
    Landslides falling into water bodies can generate destructive waves, which can be classified as tsunamis. An experimental facility to study this phenomenon has been set up. It consists of a landslidegenerator releasing ...
