    • A note on a family of non-gravitational central force potentials in dimension one 

      Alvarez-Ramírez, M.; Corbera Subirana, Montserrat; Cors Iglesias, Josep Maria; García, A. (Elsevier, 2017-12-01)
      Article
      Accés obert
      In this work, we study a one-parameter family of differential equations and the different scenarios that arise with the change of parameter. We remark that these are not bifurcations in the usual sense but a wider phenomenon ...

    • Effect of collisions on the particle behavior in a turbulent square duct flow 

      Zhang, Hao; Trias Miquel, Francesc Xavier; Gorobets, Andrei; Oliva Llena, Asensio; Yang, Dongmin; Tan, Yuanqiang; Sheng, Yong (2015-01-01)
      Article
      Accés restringit per política de l'editorial
      The effect of collisions on the particle behavior in a fully developed turbulent flow in a straight square duct at Re-r = 300 is numerically investigated. The hydrodynamic modeling of the fluid phase is based on direct ...

    • Second species periodic solutions for the three body problem 

      Lamas Rodríguez, José (Universitat Politècnica de Catalunya, 2020-07)
      Projecte Final de Màster Oficial
      Accés obert
      We are going to explain the construction of second-species periodic solutions for the Restricted Planar Circular 3-Body Problem. These solutions, whose existence had been conjectured by Poincaré, are referred to periodic ...

    • Smoothed Particle Hydrodynamics simulations of white dwarf close encounters in dense stellar systems 

      Aznar Siguan, Gabriela (Universitat Politècnica de Catalunya, 2011-09-22)
      Projecte Final de Màster Oficial
      Accés obert
      English: In old dense stellar systems collisions of white dwarfs are a rather frequent phenomenon. Here we present the results of several Smoothed Particle Hydrodynamics simulations of close encounters of white dwarfs to ...
