A Phase-field model study of two-dimensional dendritc growth in thermal solidification processes Martínez González, Gustavo Universitat Politècnica de Catalunya. Departament de Física Aplicada González Cinca, Ricardo Àrees temàtiques de la UPC::Física::Física de fluids Fluid dynamics Solidification Phase Field Dendritic Solidification Dinàmica de fluids Solidificació A 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 implemented and their stability regions have been compared. Different regimes of dendritic growth have been obtained from simulations, showing a good qualitative agreement with experimental observations. The dependence of the velocity and direction of growth on the system undercooling has been numerically obtained for a specific case. 2008-06-19 Master thesis https://hdl.handle.net/2099.1/5726 eng http://creativecommons.org/licenses/by-nc-nd/2.5/es/ Open Access Attribution-NonCommercial-NoDerivs 2.5 Spain application/pdf Universitat Politècnica de Catalunya
