  • Reshaping of large aeronautical structural parts: a simplified simulation approach 

    Mena Andrade, Ramiro; Aguado, José Vicente; Guinard, S.; Huerta, Antonio (American Institute of Physics (AIP), 2018)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    Large aeronautical structural parts present important distortions after machining. This problem is caused by the presence of residual stresses, which are developed during previous manufacturing steps (quenching). Before ...

    Stronger student engagement or improved student engagement are common instructional objectives expressed by Higher Educational Institutions. They aim, in particular, at reducing the early dropouts of Science, technology, ...

  • Alternative Trajectory Options for Delay Reduction in Demand and Capacity Balancing 

    Xu, Yan; Dalmau Codina, Ramon; Melgosa Farrés, Marc; Villardi de Montlaur, Adeline de; Prats Menéndez, Xavier (2018)
    Text en actes de congrés
    Accés obert
    Aiming to a more collaborative demand and capacity balancing (DCB), in the scope of trajectory based operations, this paper presents an approach that takes alternative trajectories into a DCB optimization algorithm. ...

  • Impact study of contact angle boundary conditions for CFD simulation of two-phase flow generation in a T-junction 

    Arias Calderón, Santiago; Villardi de Montlaur, Adeline de (2017)
    Comunicació de congrés
    Accés obert
    Gas – liquid two - phase flows dominated by capillary forces occur in countless modern industrial applications. Some examples can be found in normal gravity (mixing process, chemical reactions, ...

  • Discrete element modelling of granular column collapse tests with industrial applications 

    Torres Serra, Joel; Tunuguntla, Deepak R.; Denisen, Irana; Rodríguez Ferran, Antonio; Romero Morales, Enrique Edgar (International Centre for Numerical Methods in Engineering (CIMNE), 2017)
    Text en actes de congrés
    Accés obert
    Describing the behaviour of granular materials is a challenging issue for the industry. Our work concerns packaging industries where packing equipment is designed to handle a wide range of powders and bulk solids with ...

  • Flowability of granular materials with industrial applications: an experimental approach 

    Torres Serra, Joel; Romero Morales, Enrique Edgar; Rodríguez Ferran, Antonio; Caba, Joan; Arderiu, Xavier; Padullés, Josep-Manel; González, Juanjo (EPJ Web of Conferences, 2017)
    Text en actes de congrés
    Accés obert
    Designing bulk material handling equipment requires a thorough understanding of the mechanical behaviour of powders and grains. Experimental characterization of granular materials is introduced focusing on flowability. A ...

  • An augmented Lagrangian formulation to impose boundary conditions for distortion based mesh moving and curving 

    Ruiz Gironès, Eloi; Gargallo Peiró, Abel; Sarrate Ramos, Josep; Roca Navarro, Xevi (Elsevier, 2017)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    We formulate a mesh morphing technique as mesh distortion minimization problem constrained to weakly satisfy the imposed displacement of the boundary nodes. The method is devised to penalize the appearance of inverted ...

  • Approximation of immersed surfaces into a tetrahedral mesh generated by the meccano method 

    Socorro Marrero, Guillermo Valentín; Oliver Serra, Albert; Ruiz Gironès, Eloi; Cascón Barbero, José Manuel; Rodriguez Barrera, Eduardo; Escobar Sánchez, José M.; Montenegro Armas, Rafael; Sarrate Ramos, Josep (2017)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    In this paper, we present a new method to insert open surfaces into an existing tetrahedral mesh generated by the meccano method. The surfaces must be totally immersed in the mesh and must not intersect between them. The ...

  • Educating XXIst century civil engineers in Barcelona 

    Turmo Coderque, José; Estela Carbonell, M. Rosa; Chacón Flores, Rolando Antonio; Gironella Cobos, Xavier; Lloberas Valls, Oriol; Oliver Olivella, Xavier; Poblet-Puig, Jordi; Puigví Burniol, Maria Àngels; Valls del Barrio, Susanna; Díez, Pedro (2017)

    The educational programs of Civil Engineering schools have evolved to adapt to changes in society demands and regulations. Specifically, Civil Engineering curricula in Spain was highly impacted by the Bolonia Declaration ...

  • Simulating debris impacts on hydrokinetic infrastructure 

    Aliseda, A; Bagi, A; Johnson, Jerome B; Duvoy, P. X.; Kasper, J. L; Kulchitsky, A; Villardi de Montlaur, Adeline de (2017)
    Comunicació de congrés
    Accés obert
    The discrete element method was applied to model the impact force of woody debris (trees) on hydrokinetic infrastructure in a river setting. The DEM model, termed the Hydrokinetic Debris Impact Simulator (HDIS) was used ...

  • Experimental numerical correlation of subsystem contributions in the advanced transfer path analysis framework 

    Magrans Fontrodona, Francesc Xavier; Arcas, Kevin; Vicens Rodríguez, Pere; Poblet-Puig, Jordi; Rodríguez Ferran, Antonio (2017)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    In a complex vibroacoustic system the overall noise or vibration in a given location is the sum of multiple subsystem contributions. From an experimental perspective, the total noise can be directly measured but not the ...

  • Discrete meso-modeling of steel fiber reinforced concrete: simulation of flexural behavior 

    Pros Parés, Alba; Díez, Pedro; Molins i Borrell, Climent (International Centre for Numerical Methods in Engineering (CIMNE), 2011)
    Text en actes de congrés
    Accés obert
    Concrete provides with a variety of innovative designs, but two characteristics have limited its use: it is brittle and weak under tension. One way to overcome this problem is to add steel fibers into the concrete matrix, ...
