A finite element method solution to the phase-field model of the Stefan problem
(2022-12-20)
Article
Accés obertThis work is concerned with the Phase-Field model of the Stefan problem, as well as the numerical solution with the Finite Element Method to simulate examples in two dimensions. -
A molecular simulation study on transport properties of FAMEs in high-pressure conditions
(Elsevier, 2022)
Article
Accés obertTransport property prediction of fatty acid methyl esters (FAMEs) is essential to its utilisation as biodiesel and biolubricant which can work under high-pressure conditions. Equilibrium molecular simulation is performed ... -
A Phase-field model study of two-dimensional dendritc growth in thermal solidification processes
(Universitat Politècnica de Catalunya, 2008-06-19)
Projecte Final de Màster Oficial
Accés obertA phasefield model in two dimensions with both surface energy and kinetic anisotropies is used to simulate dendritic solidification of a pure material from its undercooled melt. Two finite differences methods have been ... -
A phenomenological model for the solidification of eutectic and hypoeutectic alloys including recalescence and undercooling
(2018-05)
Article
Accés obertIn this work, a novel phenomenological model is proposed to study the liquid-to-solid phase change of eutectic and hypoeutectic alloy compositions. The objective is to enhance the prediction capabilities of the solidification ... -
EBSD texture analysis of an AlCuMg alloy for different solidification rates
(2012)
Text en actes de congrés
Accés obertThe 3xx series aluminium alloys are widely used for automotive applications. However, increments in engine power density result in higher alloy mechanical properties requirements for components such as cylinder heads. ... -
Fixed-grid numerical modeling of melting and solidification using variable thermo-physical properties - Application to the melting of n-Octadecane inside a spherical capsule
(2015-07-01)
Article
Accés obertA fixed-grid enthalpy model for unstructured meshes and explicit time integration schemes (Galione et al., 2014) is here extended for taking into account the change in density and other thermo-physical properties with the ... -
Het diffusion anisotropy in dendritic growth: phase field simulations and experiments in liquid crystals
(Elsevier, 1998-10-15)
Article
Accés restringit per política de l'editorialAn anisotropic heat diffusion coefficient is introduced in order to study some interfacial growth phenomena. This anisotropy has been incorporated in a phase field model which has been studied numerically to reproduce some ... -
Inoculation of Primary Austenite in Grey Cast Iron
(Universitat Politècnica de Catalunya / Högskolan I Jönköping, 2008)
Projecte/Treball Final de Carrera
Accés restringit per acord de confidencialitat -
Non-equilibrium molecular dynamics and continuum modelling of transient freezing of atomistic solids
(2021-01)
Article
Accés obertIn this work we investigate the transient solidification of a Lennard-Jones liquid using non-equilibrium molecular dynamics simulations and continuum heat transfer theory. The simulations are performed in slab-shaped boxes, ... -
Pattern formation during mesophase growth in a homologous series
(American Physical Society, 1996-08-01)
Article
Accés restringit per política de l'editorialRemarkable differences in the shape of the nematic-smectic-B interface in a quasi-two-dimensional geometry have been experimentally observed in three liquid crystals of very similar molecular structure, i.e., neighboring ... -
Phase field simulations and experiments of faceted growth in liquid crystals
(Elsevier Science, 1996-12-01)
Article
Accés restringit per política de l'editorialWe present numerical simulations directed at the description of smectic-B germs growing into the supercooled nematic phase for two different liquid crystalline substances. The simulations are done by means of a phase-field ... -
The behavior of radiogenic particles at solidification fronts
(Elsevier, 2016-12-20)
Article
Accés obertThe thermal behavior of insoluble radiogenic particles at the solid-liquid interface of an advancing solidification front and its significance with regard to environmental impact are discussed. It is shown that, unlike ...
