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
Accés obertThe 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
Accés obertThis 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
Accés obertA 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)
Text en actes de congrés
Accés obertA 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)
Tesi
Accés obertThe 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
Accés obertAn 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)
Projecte/Treball Final de Carrera
Accés obertGaia 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 ...
