    Flowability of powders and bulk solids is critical for the packaging industry in the selection and design of bulk material handling equipment. Nowadays, a variety of feeder systems are used for dosing operations in bagging ...

  • Hygroscopicity issues in powder and grain technology 

    Torres Serra, Joel; Romero Morales, Enrique Edgar; Rodríguez Ferran, Antonio (The Hong Kong University of Science and Technology (HKUST), 2018)
    Conference report
    Open Access
    The effect of hygroscopicity on flowability of powders and bulk solids with applications in the packaging industry is experimentally and numerically investigated. Firstly, four granular materials are tested at different ...

  • Caracterización numérica y experimental de un sistema vibroacústico mediante "Advanced Transferer Path Analysis" 

    Cierco, Ester; Vicens Rodríguez, Pere; Aragonès Martín, Àngels; Arcas, Kevin; Poblet-Puig, Jordi; Magrans Fontrodona, Francesc Xavier; Rodríguez Ferran, Antonio (Sociedad Española de Acústica, 2018)
    Conference report
    Restricted access - publisher's policy
    ATPA (Advanced Transfer Path Analysis) is a method that allows knowing the noise paths and contributions of a vibroacoustic problem. It is clear that a good quantification of the less dominant contributions is essential ...

  • Arrival trade-offs considering total flight and passenger delays and fairness 

    Villardi de Montlaur, Adeline de; Delgado Muñoz, Luis (2018)
    Conference report
    Restricted access - publisher's policy
    This paper studies trade-offs between flight and passenger delays and fairness when assigning delay pre-tactically (on-ground at origin airport) due to reduced airport capacity. The paper also defines and analyses ...

  • Cell-DEVS modeling and simulation of artificial hydraulic fracturing of rocks in boreholes (WIP) 

    Oyelowo, I.; Wainer, G.; Echegini, N.S.; Ukeme, J.B.; Zlotnik, Sergio (Society for Computer Simulation International, 2018)
    Conference report
    Restricted access - publisher's policy
    Hydraulic Fracturing is a technique used in the extraction and exploration of oil and gas. During hydraulic fracturing, a high-pressure fluid is injected into a wellbore; this fluid flows through some artificially made ...

  • 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)
    Conference report
    Restricted access - publisher's policy
    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 ...

  • Engagement of civil engineer students in the first academic year 

    Estela Carbonell, M. Rosa; Díez, Pedro (International Centre for Numerical Methods in Engineering (CIMNE), 2018)
    Conference report
    Open Access
    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)
    Conference report
    Open Access
    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)
    Conference lecture
    Open Access
    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)
    Conference report
    Open Access
    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)
    Conference report
    Open Access
    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, Francisco Javier (Elsevier, 2017)
    Conference report
    Restricted access - publisher's policy
    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 ...
