    • A finite volume method to solve the frost growth using dynamic meshes 

      Bartrons Casademont, Eduard; Oliet Casasayas, Carles; Gutiérrez Álvarez, Enrique; Naseri, Alireza; Pérez Segarra, Carlos David (2018-09-01)
      Article
      Open Access
      The physical mechanisms of frost formation have been widely studied, yet much empirism is still needed in numerical approaches. Indeed, accurate simulations of frost growth can be reached by setting up a specific combination ...
    • A semi-implicit coupling technique for fluid–structure interaction problems with strong added-mass effect 

      Naseri, Alireza; Lehmkuhl Barba, Oriol; González Acedo, Ignacio; Bartrons Casademont, Eduard; Pérez Segarra, Carlos David; Oliva Llena, Asensio (2018-07-01)
      Article
      Open Access
      This paper is concerned with the numerical simulation of fluid–structure interaction problems involving an incompressible viscous flow and an elastic structure. A semi-implicit coupling technique is presented which strongly ...
    • Fixed grid numerical modelling of frost growth and densification 

      Bartrons Casademont, Eduard; Galione, Pedro; Pérez Segarra, Carlos David (2019-03)
      Article
      Open Access
      A fixed-grid-porous-media method capable of simulating the growth and densification of frost sheets is here presented. A velocity field is calculated across the entire domain, in which a porous media treatment is given to ...
    • Frost formation: optimizing solutions under a finite volume approach 

      Bartrons Casademont, Eduard; Pérez Segarra, Carlos David; Oliet Casasayas, Carles (Institute of Physics (IOP), 2016)
      Conference report
      Open Access
      A three-dimensional transient formulation of the frost formation process is developed by means of a finite volume approach. Emphasis is put on the frost surface boundary condition as well as the wide range of empirical ...
    • Numerical simulation of frost growth and densification using deformable and static grids 

      Bartrons Casademont, Eduard (Universitat Politècnica de Catalunya, 2018-10-05)
      Doctoral thesis
      Open Access
      The present thesis aims at developing a basis for the numerical simulation of the growth and densification of macroscopic frost sheets. Notwithstanding the fact that icing has still a long way to fully understand its ...
    • Numerical study of Taylor bubbles rising in a stagnant liquid using a level-set/moving-mesh method 

      Gutiérrez González, Ernesto; Balcázar Arciniega, Néstor; Bartrons Casademont, Eduard; Rigola Serrano, Joaquim (2017-06-08)
      Article
      Open Access
      An Arbitrary Lagrangian-Eulerian formulation has been posed to solve the challenging problem of the three-dimensional Taylor bubble, within a Conservative Level Set (CLS) framework. By employing a domain optimization method ...
    • The impact of jitter on the scanning law of Gaia 

      Bartrons Casademont, Eduard (Universitat Politècnica de Catalunya, 2009-02-25)
      Master thesis (pre-Bologna period)
      Open Access
      Gaia is an ambitious mission of the European Space Agency (ESA). Its main objective is to obtain a three-dimensional map of the Milky Way. Gaia will reveal the composition of the Galaxy and the way in which it was formed ...
