Numerical study of heat transfer from a wall incorporating a phase change material

Abstract

A numerical study of the thermal behavior of walls made up of construction materials used in Algeria and walls containing a phase change materials is presented. The model, based on the enthalpy formulation, is described by an equation of heat transfer. This equation is solved by an implicit method of finite differences and algorithm of Thomas. We analyzed the influence of the wall’s thickness and its composition on the evolution during the time of the temperature of the inside face of thewall.
