  • Review of Lambert's problem 

    De La Torre Sangrà, David; Fantino, Elena (2015)
    Conference lecture
    Open Access
    Lambert’s problem is the orbital boundary-value problem constrained by two points and elapsed time. It is one of the most extensively studied problems in celestial mechanics and astrodynamics, and, as such, it has always ...
  • Analysis of perturbations and station-keeping requirements in highly-inclined geosynchronous orbits 

    Fantino, Elena; Flores Le Roux, Roberto Maurice; Di Salvo, Alessio; Di Carlo, Marilena (2015)
    Conference report
    Open Access
    There is a demand for communications services at high latitudes that is not well served by conventional geostationary satellites. Alternatives using low-altitude orbits require too large constellations. Other options are ...
  • A meshless finite point method for three-dimensional analysis of compressible flow problems involving moving boundaries and adaptivity 

    Ortega, Enrique; Oñate Ibáñez de Navarra, Eugenio; Idelsohn Barg, Sergio Rodolfo; Flores Le Roux, Roberto Maurice (2013-10)
    Article
    Open Access
    A finite point method for solving compressible flow problems involving moving boundaries and adaptivity is presented. The numerical methodology is based on an upwind-biased discretization of the Euler equations, written ...
  • Three-dimensional numerical simulation of an external gear pump with decompression slot and meshing contact point 

    Castilla López, Roberto; Gámez Montero, Pedro Javier; Campo Sud, David del; Raush Alviach, Gustavo Adolfo; García Vilchez, Mercedes; Codina Macià, Esteban (2015-04-01)
    Article

    Recently several works have been published on numerical simulation of an external gear pump (EGP). Such kinds of pumps are simple and relatively inexpensive, and are frequently used in fluid power applications, such as ...
  • Modelling harmonics drawn by nonlinear loads 

    Lamich Arocas, Manuel; Balcells Sendra, Josep; Mon González, Juan; Corbalán Fuertes, Montserrat; Griful Ponsati, Eulàlia (Institute of Electrical and Electronics Engineers (IEEE), 2015)
    Conference report

  • Preliminary study on fluidic actuators. Design modifications 

    Campo Sud, David del; Bergadà Granyó, Josep Maria; Campo Gatell, Vanessa del (2015)
    Conference report

    As fluidic actuators have the advantage of lacking moving parts, their use in real applications brings high reliability. This is why, once having overcome their drawbacks, which means being able to provide the appropriate ...
  • A simulation tool for parachute/payload systems 

    Flores Le Roux, Roberto Maurice; Ortega, Enrique; Vallés Fluvià, J.; Oñate Ibáñez de Navarra, Eugenio (Centre Internacional de Mètodes Numèrics en Enginyeria (CIMNE), 2014)
    Conference report

    The design and evaluation of parachute-payload systems is a technology field in which numerical analysis tools can make very important contributions. This work describes a new development from CIMNE in this area, a coupled ...
  • Pressure effects on the performance of external gear pumps under cavitation 

    Campo Sud, David del; Castilla López, Roberto; Raush Alviach, Gustavo Adolfo; Gámez Montero, Pedro Javier; Codina Macià, Esteban (2014-11)
    Article
    Restricted access - publisher's policy
    The numerical analysis of an external gear pump with cavitation effects has been validated with experimental data obtained by applying Time-Resolved Particle Image Velocimetry. The effect of inlet and outlet pressure on ...
  • Holistic indices for productivity control assessment, applied to the comparative analysis of PID and fuzzy controllers within an Isasmelt furnace 

    Ojeda Sarmiento, Juan Manuel; Fuertes Armengol, José Mª; Griful Ponsati, Eulàlia (2014-02-01)
    Article
    Restricted access - publisher's policy
    This research aims to contribute to the analysis of control performance assessment in extractive metallurgy. Productivity-based indices are proposed in addition to current measuring techniques. Such criteria are employed ...
