Unstructured modelling of solid-liquid phase change using parallel computing. Application to the analysis of thermal energy storage systems with encapsulated phase change materials

Abstract

The main goal of this work is to numerically simulate convection phenomena in solid-liquid phase change processes and its application in the analysis of a thermal energy storage system with phase change materials. First two chapters consist in the resolution of two well-known numerical problems used as an introduction to the governing equations of uid ows and heat transfer. Here, the necessary tools for discretizing and solving these equations are brie y described. Third chapter speci cally deals with the problem of modelling solid-liquid phase change and its application into the simulation of a special thermal storage system.
