Hygroscopicity issues in powder and grain technology
(The Hong Kong University of Science and Technology (HKUST), 2018)
Text en actes de congrés
Accés obertThe 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"
(Sociedad Española de Acústica, 2018)
Text en actes de congrés
Accés restringit per política de l'editorialATPA (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
(2018)
Text en actes de congrés
Accés restringit per política de l'editorialThis 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)
(Society for Computer Simulation International, 2018)
Text en actes de congrés
Accés restringit per política de l'editorialHydraulic 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
(American Institute of Physics (AIP), 2018)
Text en actes de congrés
Accés restringit per política de l'editorialLarge 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
(International Centre for Numerical Methods in Engineering (CIMNE), 2018)
Text en actes de congrés
Accés obertStronger 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
(2018)
Text en actes de congrés
Accés obertAiming 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
(2017)
Comunicació de congrés
Accés obertGas – 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
(International Centre for Numerical Methods in Engineering (CIMNE), 2017)
Text en actes de congrés
Accés obertDescribing 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
(EPJ Web of Conferences, 2017)
Text en actes de congrés
Accés obertDesigning 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
(Elsevier, 2017)
Text en actes de congrés
Accés restringit per política de l'editorialWe 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
(2017)
Text en actes de congrés
Accés restringit per política de l'editorialIn 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 ...
