  • Heuristics of node selection criteria to assess robustness of world airport network 

    Soria Guerrero, Manel; Lordan González, Oriol; Sallán Leyes, José María (2017-06-14)
    Open Access
    The world airport network (WAN) is one of the networked infrastructures that shape today's economic and social activity, so its resilience against incidents affecting the WAN is an important problem. In this paper, the ...
  • Three dimensionality in the wake of the flow around a circular cylinder at Reynolds number 5000 

    Aljure Osorio, David E.; Lehmkuhl, Oriol; Rodríguez Pérez, Ivette María; Oliva Llena, Asensio (Elsevier, 2017-04-02)
    Restricted access - publisher's policy
    The turbulent flow around a circular cylinder has been investigated at Re=5000Re=5000 using direct numerical simulations. Low frequency behavior, vortex undulation, vortex splitting, vortex dislocations and three dimensional ...
  • Rotor spinning transfer channel design optimization via computational fluid dynamics 

    Huiting, Lin; Bergadà Granyó, Josep Maria; Yongchun, Zeng; Nicholus T, Akankwasa; Yuze, Zhang; Jun, Wang (2017-03-16)
    Open Access
    The conventional rotor spinning unit generates flow vortices in the transfer channel upstream region which affect the fiber configuration and consequently yarn properties. Geometry and spinning parameters such as transfer ...
